The document discusses different modes of conducting surveys, including traditional, interview-based, email-based, web-based, mobile-based, and SMS-based surveys. It finds that SMS-based surveys provide the best solution in terms of time, cost and response rate compared to other modes. However, SMS-based surveys also have limitations like limited characters per SMS. The study concludes that existing survey modes need improvement to get maximum responses quickly at lowest cost. It contributes to understanding factors like cost, time and response rate for different survey modes.
Understanding User’s Acceptance of Personal Cloud Computing: Using the Techno...Maurice Dawson
Personal Cloud Computing (PCC) is a rapidly growing technology, addressing the market demand of individual users for access to available and reliable resources. But like other new technologies, concerns and issues have surfaced with the adoption of PCC. Users deciding whether to adopt PCC may be concerned about the ease of use, usefulness, or security risks in the cloud. Negative attitudes toward using a technology have been found to negatively impact the success of that technology. The purpose of this study was to understand users’ acceptance of PCC. The population sample consisted of individual users within the United States between 18 and 80 years of age. The theoretical framework utilized in this study was based on the technology acceptance model (TAM). A web survey was conducted to assess the measurement and understanding of patterns demonstrated by participants. Our results shows that in spite of the potential benefits of PCC, security and privacy risks are deterring many users from moving towards PCC.
A web-based survey and theoretical research focuses mainly on the hazards that children are exposed to while surfing the digital world. It addresses the problem from parents/caregivers perspective and tries to shed light over the best ways of understanding and precautionary means. It is important for families to take all preventive measures to protect their kids from such hazards.

PIU can be defined as “use of the Internet that creates psychological, social, school, and/or work difficulties in a person's life”. The main aim of the present study is to investigate the differentiation situation of PIU levels with respect to gender, age, Internet usage time, having a tablet, computer, smartphone, Internet access at home and purpose of Internet usage. Analyses are created with t-test and one-way variance analysis (ANOVA). The Results has shown that PIU level is higher for boys, older age, have higher Internet usage time, Internet access at home, a computer, a smartphone and use the Internet for entertainment. In addition, groups using the Internet for entertainment have higher PIU level than those who do not use Internet for these purposes. Backwords, the groups using the Internet for doing homework/school project, searching a subject for his/her own personal interest and for reading have lower PIU level than those who do not use the Internet for these purposes.

A Multimedia Data Mining Framework for Monitoring E-Examination Environmentijma
Academic dishonesty has been a growing concern in e-learning environment due to the fact that eexamination takes place under supervised and unsupervised learning environment despite its huge advantages. The e-examination environment has faced various security breaches such as academic dishonesty (impersonation), identity theft, unauthorised access and illegal assistance as a result of inefficient measures employed. Hence, an efficient framework which will aid the monitoring of the eexamination is needed. This paper reviews the process of mining multimedia data and propose a framework for monitoring the e-examination environment in order to extract images and audio features. The framework has four major phases: data pre-processing, mining, association and post processing. The
pre-processing phases carries out the extraction and transformation of multimedia data features, the mining phase does the classification and clustering of these features, the association does pattern matching while the post processing carries out the knowledge interpretation and reporting. The approach presented in this study will allow for efficient and accurate monitoring of e-examination environment which will help provide adequate security and reduce unethical behaviour in e-examination environment.

The Climate issue will only be solved, if it can be solved, by the major nations taking a stand on production of fossil fuels, just as they did for the elimination of CFCs through the Montreal Protocol in 1987. Setting limits on production will drive the behavioral and technological change needed to really bring about a shift in our global emissions profile. While we wait for that to happen, we need to get on and start creating long-term adaptation and resilience strategies. Forget about saving the planet, it's time to save ourselves.

Chapter 5: Survey Research: Questionnaires
Chapter 6: Survey Research: Interviews and Telephone Surveys
Unit Lesson
As we learned in previous units, there are multiple ways to collect the data. One of the most popular methods
of collecting data is survey research. This widely used technique allows the researcher to collect a variety of
information from study participants, regardless of whether the identity of the participants is known.
Questionnaires, interviews, and telephone surveys are three primary forms of survey research.
Questionnaires
There are many ways to develop a questionnaire. However, there are some rules and guidelines that exist to
help a researcher develop questionnaires that will properly collect the data that he or she needs to address
the research questions. Most of the guidelines focus on the wording and construction of questionnaires. When
developing a questionnaire, one should be aware of the question types. Wording configurations that should
be avoided include biased or leading questions, double-barreled questions, questions asked objectively,
assumptions regarding the respondent’s knowledge regarding issues, vague wording, collecting excessive
information, and “response set” (Hagan, 2014).
The organization of the questionnaire is also important. Questionnaires should normally begin with questions
that focus on the study topic and how they sit with demographic type questions such as age, race/ethnicity,
income, and occupation. For example, if you were interested in looking at the relationship in the number of
children involved in community policing activities, then make sure the survey begins with questions that ask
specifically about their level of involvement in the community and/or the extent of their interaction with police
in the community. Then, end a survey by asking them questions about their family such as how many people
are in their household, how many of those people are children, and what are the ages of the children in the
household?
The manner in which the questionnaire is administered is also important. Questionnaires can be given directly
to the participant, mailed to the participant, and electronically provided to the participant (e.g., link or QSR
code). Mail surveys are a very popular method of.
A large scale study of daily information needs captured in situWookjae Maeng
The goal of this work is to provide a fundamental understanding of the daily information needs of people through a large-scale, in-depth, quantitative investigation. To this end, we have conducted one of the most comprehensive studies of information needs to date, spanning a 3-month period and involving more than 100 users. The study employed a contextual experience sampling method, a snippet-based diary technique using SMS technology, and an online Web diary to gather in situ insights into the types of needs that occur from day to day, how those needs are addressed, and how contextual, technological, and demographic factors impact on those needs. Our results not only complement earlier studies but also provide a new understanding of the intricacies of people’s daily information needs.

MARKETING RESEARCH
Market research is a systematic way to gather, evaluate and present it in a form that explains various facts and figures to the business. Collected information acts as a vital tool to have increments in business activities, qualitative work done and improved profits. Any company, whether small scale or large scale, can perform market research before marketing its products or services. It can also be useful when launching a new product or diversifying the business. It is useful as well when a company has to expand its business globally. It avails numerous benefits to the businesses.
Among the different methods of data gathering for research purposes, many researchers due to its various advantages, strengths and benefits prefer the survey method. However, surveys also have their disadvantages and weak points that must be considered.
Advantages of Marketing Surveys
Market research is a scheduled method to collect, analyze and correlate beneficial data for the benefit of business to make strategic decisions. Collected information acts as a vital tool to have increments in business activities, qualitative work done and improved profits. Any company, whether small scale or large scale, can perform market research before selling its products or services. It can also be useful when launching a new product or diversifying the business. It is useful as well when a company has to expand its business globally. It avails numerous benefits to the companies.
Among the different methods of data gathering for research purposes, many researchers due to its various advantages, strengths and benefits prefer the survey method. However, surveys also have their disadvantages and weak points that must be considered.
Online surveys and mobile surveys tend to be the most cost-effective modes of survey research, yet they may not reach those respondents that can only respond using alternate modes. Results of online surveys and mobile surveys may suffer and differ greatly if important respondents are left out of the research. Hard-to-reach respondents may be easier to reach using more traditional methods such as paper surveys or face-to-face interviews. The self-completed postal or mail survey is a recognized form of data collection in marketing research (Dillman 1978). There are well- documented practical problems with this form of data collection: poor response rates, slow response, and manual transcription of data from a hard copy questionnaire to an appropriate statistical analysis tool. Non- response and data entry errors may result. Consequently, research into online data collection methods increased significantly during the late 1990s. This was preceded by (1) a growing number of Internet and email users, which started ...

Changes in survey mode for conducting panel surveys may contribute significantly to
survey error. This article explores the causes and consequences of such changes in
survey mode. The authors describe how and why the choice of survey mode often
causes changes to be made to the wording of questions, as well as the reasons that
identically worded questions often produce different answers when administered
through different modes. The authors provide evidence that answers may change as a
result of different visual layouts for otherwise identical questions and suggest ways
to keep measurement the same despite changes in survey mode.
Keywords: survey mode; questionnaire; panel survey; measurement; survey error
Most panel studies require measurement of the same variables at different
times. Often, participants are asked questions, several days, weeks, months,
or years apart to measure change in some characteristics of interest to the
investigation. These characteristics might include political attitudes, satis-
faction with a health care provider, frequency of a behavior, ownership of
financial resources, or level of educational attainment. Whatever the charac-
teristic of interest, it is important that the question used to ascertain it perform
the same across multiple data collections.
In addition, declining survey response rates, particularly for telephone
surveys, have encouraged researchers to use multiple modes of data collec-
tion during the administration of a single cross-sectional survey. Encouraged
by the availability of more survey modes than in the past and evidence that a
change in modes produces higher response rates (Dillman 2002), surveyors

Literature Review
Since the introduction of electronic devices, the world has shifted into a new technological era with great assistance from the development of the internet. The technology then became more portable and commercial, which made the mechanisms more accessible, affordable and evidently more desirable. The popularity of these internet associated devices rose quickly and still continue to rise, as it becomes the norm for individuals to own at least one electronic device. The purpose of these devices it to assist with an individual’s daily task along with many more possibilities, and because of its influential power, questions like how it affected with the development of humans in the modern era begin to surface.
The purpose of this study is to discover how the interactions and communications between humans have evolved since the involvement of internet and electronic technology. This topic has peaked interest of many researchers, and popular themes concerning the topic includes relationships and intimacy between individuals via the internet from computers and phones. Some previous research that has been chosen to be used as references all follow along a similar pattern, regarding the sample size and diversity, methodology, and theoretical influences.
One method that is popular to the researchers in the field of sociology is known as Ethnography, which is “the systematic description of human behaviour and organizational culture based on first-hand observation” (Howard, 2002, p.553). But because of the new technological advancement, using such a traditional procedure may be unable to fully analyze the subject. One research decided to adapt to the technologic subject and develop a different form of Ethnography to accommodate any flaws the tradition method had; the new methodology is called Network Ethnography.
Network ethnography involves with passive or active observation, extended immersion, and in-depth interviews, following the processes of ethnographical research methods. The contribution Network ethnography provides is that it does not limit the researcher into choosing territorial field sites, but also has the opportunity to select multiple social networks as field sites.
Another reason why they believe Network Ethnography is a valid method of examining social behaviour and different technological mediums is that a researcher can manage sample bias whether it be extreme, snowball or any other sampling method. The reason being is that “snowball sampling for example, does not allow the researcher to control the direction of sample growth, but social network analysis will identify some of the most significant informants in the network (Howard, 2002 pg 562).” Researchers can use the in.

Main Points:
The consumer may notice that 911 is becoming more familiar with technology as well as a enhancement for the disadvantaged users that they will not question what took as long. Text-to-911 is using disabilities as a “preoccupation” or used to help promote the program. 911 emergency communication system traditional methods have failed the consumer expectations due to dropped calls, delayed reverse lookups, etc. which may have led to tragic events.
Research Questions/Purpose: The purpose of this article is to explain that the change to the traditional 911 emergency communication system I necessary for the function of life to include those who have disabilities. However, the authors make the argument that they are using people with disabilities as a pawn to promote the new feature. They are using the improvement of the system as an excuse to not address why it has taken so long.
Why and how is this infrastructural change being made sense of through disability, and for whom?
Methods: Archive of Educational Material
Sample: 911 communication material such as Public Service Announcement, Brochures and web pages from the Federal Communications Commission and the National Number Association.
Variables: The change of media and technical design from the perspective of people with disabilities.
Procedure: The use of dismediation and analyzing the media looking at the information from an infrastructure perspective.
Results:
Statistical Test:
Findings: When considering the ability to talk to 911 or have a peaceful encounter with the police or 911 emergency system is a privilege. People with disabilities are not always understood and could lead to a violent encounter because officer began to assume, they are not cooperating. Although this a infrastructural change for everyone to the emergency communication system, they use disabilities as a way to justify the change and it will not be questioned.
Discussion/Interpretation:
The limitations that have been placed in the system for years is being covered up with the introduction of this new system. It has not been challenged yet and consumers will not challenge it because there was a infrastructural change.
Problems: Th argument seemed to be one sided and the author assumed that consumers would not see how this advancement is very essential if they do not have a disability.
Take home message: Technology has become domesticated by societies demand and Text-to-Call is trying to implement it into their system. 911 system has withstood being domesticated for people with thick accents or people with disabilities.
Notable Quotes:
Ultimately, I argue that in these materials, deafness and disability function as what Mara Mills refers to as an "assistive pretext" (2010)--a preoccupation--that discursively refra ...

Abstract
Fresh, bias-free and valid data collected using different survey modes is considered an essential requirement
for smooth functioning and evolution of an organization. Surveys play a major role in making in-time and correct
decisions and generating reports. The aim of this study is to compare and investigate state-of-the-art in
different survey modes including print, email, online, mobile and SMS-based surveys. Results indicate that
existing methods are neither complete nor sufficient to fulfill the overall requirements of an organization
which primarily rely on surveys. It also shows that SMS is a dominant method for data collection due to its
pervasiveness. However, existing SMS-based data collection has limitations like limited number of
characters per SMS, single question per SMS and lake of multimedia support. Recent trends emphasis on
smartphones applications for data collection. However, in developing countries low-end mobile devices are
still extensively used which makes the data collection difficult from man in the street. The paper concludes
that existing survey modes and methods need an improvement to get maximum responses quickly in the
lowest possible cost. The study has contributed to the area of surveying and data collection by analysing
different factors such as cost, time and response rate. The results of this study can help practitioners in
creating new methods and tools for data collection that can be effectively used for low budget projects in
developed as well as developing countries.
Keywords: Mail-based surveys, Online surveys, Mobile-based surveys.
1. Introduction
The availability of fresh, biased-free and valid data is an essential requirement for smooth
functioning of an organization. Many non-profit and governmental organizations have
undertaken a huge variety of projects in developing countries for different areas
particularly in health, education, and poverty reduction. These organizations primarily
rely on survey research for data collection (Hartung, 2012). The freshness and validity of
data is totally dependent on its collection method. Survey research is one of the most

popular and widely used methods for collecting data (Pfleeger and Kitchenham, 2001).
Survey research can be conducted in different modes and is normally dependent on time,
cost and response rates. Surveys conducted in traditional manners are time consuming
and a costly job (Cobanoglu et al., 2001). Email and World Wide Web (WWW), also
known as electronic surveys are alternative approaches for surveying. However,
electronic surveys suffers from spam-mail problems and low-response rate (Evans and
Mathur, 2005). The popularity of mobile technologies enabled a user to conduct efficient
and low cost surveys in less time. However, mobile-based data collection has limitations
as well, which are discussed in later sections. Researchers suggest the use of SMS-based
data collection as a solution to the problems associated with mail, email and web-based
surveys. However, existing SMS-based survey has limitations including limited
characters per SMS (Brown et al., 2007), single question per SMS and lack of multimedia
support. There is no single best mode of data collection that can fulfill the overall
requirements of a surveyor. So mixed mode will continue to play an important role in
survey research and data collection (Couper, 2011). Figure.1 is constructed in the light of
existing literature and survey conducted in this paper. This shows survey modes and
usage in terms of time, cost and response rate.
Cost, time and good response rate are major concerns for any type of surveys including
large-scale multinational surveys. Figure.1 shows that among all survey modes, SMS-
based survey provides a best survey solution in terms of time, cost and response rate.

2. Conducting Surveys: An Overview
Survey is a type of quantitative research instrument that is used not only for data
collection or information about an issue or phenomena, but a series of comprehensive
steps for collecting information to describe, explain or compare knowledge, attitude and
behaviour in certain circumstances. This type of research is a straightforward and
effective method used by researchers to collect information about product, brand, context,
event, employees and workers (Pfleeger and Kitchenham, 2001). Being a data collection
tool a survey is capable of gathering demographics data from large sample of populations
(Priscilla, 2005). Two popular methods for conducting survey research are questionnaire
and interview (William M.K. 2006). In questionnaire-based approach, data is collected
using pre-planned questions where responses are collected and analysed, while in
interview-based approach an interview is conducted with a number of selected
respondents and their live responses are collected and analysed.
In selection of any survey mode, the following errors must be kept in mind and should be
minimized for obtaining accurate results (Dillman, 1991). An example is the sampling
error, which occurs when the population is huge and heterogeneous. Web-based surveys
in which the population is huge and heterogeneous are more affected by this type of
errors and are difficult to overcome (Van Selm and Jankowski, 2006). To overcome this
type of error up to some level, some heterogeneous members are excluded from the
population for making the population homogeneous (Dillman, 1991). Recently, survey
researchers are taking keen interests in social networking sites such as Facebook etc.,
because of huge number of users. However, social media users are not the true
representatives of target population (Couper, 2011). The non-coverage errors occurs, if
the selected sample has no chance to respond (Dillman, 1991). Online surveys have
suffered a lot from this type of errors because of internet coverage especially in
developing countries (Balabanis et al., 2007). The chances of occurrence of this type of
error in mail-based surveys are low, because of the global availability of post offices
(William K. P, 2004). While in Web-based it is high because of internet coverage bias
(Couper, 2000). The non-response error occurs mostly in electronic-based surveys. The
response rate in traditional mail based survey is high (Evans and Mathur, 2005). While in
Web-based surveys response rate is low as compare to any other modes like mail, e-mail,
fax, SMS(Poole and Loomis, 2009; (Dillman, 1991)). This is because non-response error
is directly proportional to non-coverage error. If there is no internet coverage, then non-
response error gets high. Measurement errors occur if a respondent is unable to provide
accurate information. It mostly depends on the types questions of a survey (Dillman,
1991). Interviewer bias in telephone and face-to-face interview is a type of measurement
error (Uma and Bougie, 2003). Personal likes and dislikes is also a type of measurement
error.
Different approaches can be adopted for controlling and reducing such types of errors;
specifically in internet-based/online surveys. For example, the scope of internet survey
must be correctly defined. Also, combine internet-surveys and sampling techniques for
reliability and validity of results. Target your population in advance for the purpose of
homogenising collected data. Other major concerns are careful survey design and
choosing a reliable survey service provider/ survey Web-application. Questionnaire must
be designed according to the interest of respondents; otherwise measurement error will

occur. Security and privacy must be ensured by the survey services providers. Improved
data recognition techniques must be adopted for repeated responses using cookies and
Internet Protocol (IP) addresses for removing duplicate responses from the same user
(Mingyue and Xicang, 2011). The survey services providers must provide a proper
method for publishing surveys and an ensured protection against junk-mail/spam-mail. In
developing countries, non-coverage errors must be kept in mind especially in electronic-
based surveys due to limited internet coverage.
3. Survey Modes
The term “Mode” refers to the overall system of data collection chosen for a specific
purpose. Historically, mail and face-to-face were the main modes of data collection from
1940 to 1970. In 1970 telephone surveys were widely adopted in USA and later in
Europe. In 1990, internet-based surveys began to supersede telephone surveys (Couper,
2011). In this modern age, internet-based surveys (email-based, Web-based) approaches
are also gaining popularity (Elhejaj et al., 2010). Mobile-based and SMS-based data
collection is also widely used due to its pervasiveness and simplicity. The increased
number of data collection modes and methods brings more complexity in management
and conduction. As mentioned earlier, no one can fully rely on single mode of data
collection. Mixed mode is popular and widely used for data collection (De Leeuw, E. D,
2005) and continues to evolve further (Couper, 2011). Also, Vannieuwenhuyze, 2014,
illustrated the budgetary advantages of mixed mode design in case where allowed error is
small. The Table.1 is constructed from literature discussed in this article.

5. Conducting Surveys and Data Collection: From Traditional to Mobile and SMS-based Surveys
Pak.j.stat.oper.res. Vol.X No.2 2014 pp169-187 173
3.1 Mail-based Surveys
Mail-based, also known as traditional paper-based, approach of surveying is an oldest and
most popular data collection still widely used. In this approach, paper-based
questionnaire is distributed by post or by hand. Although hand-based distribution is a
difficult job but is a more effective method for small-scale surveys. For large-scale
surveys, envelop and post offices are used. Mail-based survey mode yields higher
response rate than Web-based and email-based surveys (Poole and Loomis, 2009). This is
because of selection of a large sample size is possible, huge geographic coverage, variety
of questions may be asked and low cost per individual respondent (Evans and Mathur,
2005). The pre-notifications and follow-ups by telephones have significant effects on
response rates (Kanuk and Berenson, 1975). Also, the award of incentives has a positive
impact on response rates. Besides all mentioned benefits, the overall cost of traditional
mail-based survey is high as compared to other survey modes due to paper postage
charges, return envelope charges and data/responses entry charges. Also, it is a slow and
time consuming approach as compare to other modes of surveying (William K. P, 2004).
Other major problems includes incomplete questionnaire from respondents (Evans and
Mathur, 2005), which in turn generate fake results. Another problem is that you have to
pay to data entry operators for entry of responses. . The entry of responses is not only a
time consuming job, but also the chances of errors are high (Hartung, 2012). Analysing
the gathered data required a huge amount of money especially in this mode of surveys.
3.2 Interview-based Surveys
Interviewing is another popular method for data collection. Interview-based surveys are
usually conducted face-to-face or through telephone. There are two types of interviews
namely structured and unstructured. Structured interviews are conducted when there are
some predefined questions and objectives with a specific sequence of questions, while in
unstructured interviews random questions are asked with no special objectives. The data
collected through interview should be free from measurement error which usually occurs
if the purpose and questions of interview are not clear. Bias may also occur because of
personal likes and dislikes. Establishing trust with interviewer can reduce these biases
(Uma and Bougie, 2003). Interviews conducted through telephone have advantages of
selecting a random sample, large geographic coverage, controlled surveys process, speed
and timeliness completion of surveys, personal interaction with respondents and
technological enhancement. Besides all mentioned advantages, it is a costly approach and
is not feasible to interview a large number of peoples on national and international basis
(Uma and Bougie, 2003). Other major problems are interviewer-bias, refusal from
interview and low response rate (Evans and Mathur, 2005). Refusals and low response
rates arise due to busy schedule of respondents.
Interviews can be automated using different technologies like Computer Assisted
Interviewing (CAI), Computer Assisted Telephone Interviewing (CATI) and Computer
Assisted Personal Interviewing (CAPI). In CAI questions are flashed on computer screen
and respondents are asked to respond. While in CATI, the computer is networked with
telephones system (Uma and Bougie, 2003), where questions are normally multiple
choice questions therefore, only point-and-click is required. Interview can be self-
administered using CAPI which allows a surveyor to conduct face-to-face interviewing
6. Iftikhar Alam, Shah Khusro, Azhar Rauf, Qamruz Zaman
Pak.j.stat.oper.res. Vol.X No.2 2014 pp169-187174
using computers. Here, respondents can use their own computer with CAPI software.
After responding to all questions, responses are sent back to server. This reduces the
recording error during interview (Uma and Bougie, 2003). Using these automatic-
interview approaches, responses can be collected from all over the world in less time.
3.3 E-mail-based Surveys
In this approach an email message with attached questionnaire is sent to targeted
respondents. The respondent after answering questions may reply through an email with
attached responses to a surveyor (Van Selm and Jankowski, 2006). E-mail-based surveys
has the advantages of speed and low cost (Hayslett and Wildemuth, 2005) with higher
response rate than web-based surveys (Elhejaj et al., 2010). This is because; email is a
PUSH technology in which the message is sent to the respondent’s inbox whereas the
Web is a PULL technology in which respondent must be attached to a web page. It
should be noted that there must be a predefined list of e-mail addresses of all respondents.
As the survey can be e-mailed to many respondents with no cost, email-based surveys are
less costly however, situations where manual entry is required for data analysis, cost may
get high. Other problems reported are spam/junk mail and internet coverage bias.
Nowadays an email can be sent through an ordinary Short Message Service (SMS). This
can be done using email-to-SMS/SMS-to-email gateway which enable the sending and
receiving of email using SMS even to low-end mobile devices. The gateway can
send/receive only those emails that contain only text. Rich contents such as audio, video
cannot be delivered through SMS, because of limited number of characters per SMS. E-
mail to SMS services are offered by all mobile operators in Pakistan and is rarely used for
data collection.
3.4 Web-based Surveys
Web-based surveying is an alternate and more advanced version of mail and email-based
surveying. Today there are hundreds of web applications that offer a wide range of
surveys from simple-to-complex and free-to-commercial survey solutions. These also
offer a wide range of question types with more advanced administration options. The cost
of the Web-based survey is low if a third party (normally web survey provider) is
involved for overall survey conduction (survey preparation, distribution, response
collection and analysis). For example, free service providers like Limesurvey1
may
reduce the overall cost of a survey.
The Web-based survey is advantageous because of quick response collection and
availability of automated analysis tools. So one doesn’t need to pay to data entry
operators. The major problem of Web-based survey is low response rate due to internet
coverage bias (William K. P, 2004, (Van Selm and Jankowski, 2006)). Also, in some
situations the Web-users are not true representatives of the target population. Table.2 is
an overview of state-of-the-art in online Web-based survey applications.

Pak.j.stat.oper.res. Vol.X No.2 2014 pp169-187 175
3.5 Mobile-based Surveys
Mobile-based surveying and data collection is also a popular method used worldwide by
government agencies and Non-Governmental Organizations (NGOs). Mobile phones,
which are not only voice-based communication device but offer short message services
(SMS, instant messaging) and Web-based services and are used extensively. The mobile-
based modes are expanding rapidly due to their multi-model capabilities (Couper, 2011).
The growing cellular infrastructure and low-cost mobile phones provide an opportunity to
change traditional paper-based data collection techniques to pervasive devices like
mobiles (Hartung, 2012). The mobile data collection is based on two techniques. It may
be either browser-based or SMS-based. The browser-based data collection needs an
internet connection for sending and receiving of data. For examples Magpi2
, Open-Data-
Kit3
and OpenXdata4
offer mobile browser-based data collection. In SMS-based data
collection an ordinary 160-character-SMS is used. The cost of SMS-based survey is low
due to its pervasiveness. The responses are collected very quickly and efficiently. The
automated tool for data analysis is

also its major advantage (Rittippant et al., 2009), Balabanis et al., 2007). Besides all
mentioned advantages; both browser-based and SMS-based data collection have
limitations like mobile browser compatibility issues, mobile screen compatibility issues,
slow internet connections, limited number of characters per SMS, age factor, and low
literacy rate especially in developing countries.
3.5.1 Data Collection using Well-formatted Forms and Browsers
Internet connection and installation of survey application on mobile are mandatory in this
type of data collection. The forms can be downloaded from Web-application to a pre-
loaded survey application on mobile. In form-based approach, the data can be collected
using point-and-click approach with fewer chances of errors. However, this approach has
the same inherit problem of internet coverage bias, slow internet connections. The
following are a few well-known survey applications used for mobile and tablets.
(1) Open-Data-Kit5
: Open Data Kit is an open-source set of tools for data collection
using mobiles and tablets. In Pakistan, ODK is used for data collection by NGOs.
In Afghanistan, it was used in 2010 for fraud monitoring in elections. ODK uses
forms for data collection on mobile phones, but forms and forms-data are
downloaded and uploaded using GPRS/Internet from a user mobile phones
(Hartung et al., 2010). Internet coverage bias is likely to occur in ODK-based data
collection.
(2) Magpi / Episurveyor6
: Magpi (Ex-Episurveyor) is another well-known browser-
based application used for data collection on mobile phones. The Magpi-forms
can be downloaded to a pre-loaded Magpi-application on mobile phones. The
answers can be sent back to a surveyor using internet or SMS, for which Magpi
provides an international GMS modem number. It should be noted that forms
cannot be downloaded without GPRS/Internet connection. Only the answers can
be sent to the provided GMS modem numbers.
(3) OpenXdata7
: OpenXdata is also an open source software for data collection using
low price mobile devices. OpenXdata is an advanced and renamed version of
Epihandy8
. It uses Openrosa-and-Javarosa9
platform for data collection for J2ME
and android-based mobile phones.
(4) FrontlineSMS10
: FrontlineSMS is an open-source and free SMS management tool.
It enables two-way communication using SMS with no need of internet
connection. As SMS is available even for low-end mobile devices, therefore
FrontlineSMS is highly effective and easy way to communicate with a huge
number of peoples.

Pak.j.stat.oper.res. Vol.X No.2 2014 pp169-187 177
3.5.2 Data Collection using SMS
Short Message Service (SMS), which is considered as the most popular way of
communication in developed as well as in developing countries(Rittippant et al.,
2009),(Susanto and Goodwin, 2010). SMS is a bi-directional communication service for
sending text messages through wireless communication system. It uses GSM 7-bit
encoding with maximum capacity of 140 bytes (1120 bits/160 seven-bits characters or
140 characters using eight-bits or 70 characters using sixteen-bits for non-Latin alphabets
such as Arabic, Urdu, Chinese, Korean, Japanese languages) (Brown et al., 2007),
(Mahmoud et al., 2010).
SMS-based survey is recommended as a solution to slow, low-response rate and internet
coverage problems. SMS-based survey is best alternative to probability Web-based
surveys for high response rates (up to 56 % increase in response) (Balabanis et al., 2007).
The success indictors for SMS are low-cost and pervasiveness. SMS-based surveys are a
best way to collect quick responses (in 3.3 days), which is better than other survey modes
(Rittippant et al., 2009).
3.5.3 Web-based SMS Services for Data Collection
SMS is extensively used for alerts, public transport alerts, listening to people opinions in
most of the developed countries like Australia, Indonesia, and UK (Susanto and
Goodwin, 2010). There are some online SMS-based survey services providers mentioned
in Table 3 “Web-based SMS survey providers”. The table shows some models of Web-
based SMS survey providers. If we critically analyse Table.3, we can clearly see that
most of the service providers used inbound or outbound techniques for SMS-based data
collection. An inbound strategy invites people on TV, radio or print media while in
outbound strategy a list of pre-selected mobile numbers are provided to these third-party
survey-providers. Then third-party service providers are responsible for sending SMS
invitations, questions and alerts, collect responses and analyse the collected data using
statistical tools.

3.5.4 Limitations of Traditional SMS-based Surveys
By critically analysing the existing SMS-based survey approaches, it is clear that this
approach has some serious limitations majorly from surveyor point of view. The
quantitative evaluation of data entry and its accuracy on mobile phones shows that error-
rate for SMS is 4.8%, which is high as compared to Web-forms error-rate 4.2%(Patnaik
et al., 2009). The cost per SMS is low but target population is huge and may result in a
huge cost at the end. Even in this modern age, most people do not know how to send and
open SMS (Rittippant et al., 2009)). Studies shows that SMS-based surveys appealing to
young and educated personals and nearly ignore the rest of population (Balabanis et al.,
2007). Another potential disadvantage of SMS is its limited text format (Rettie and Brum,
2001), only 140 octets “160 characters of 7-bits” as discussed. Therefore, we cannot send
rich content like audio, video and colour pictures to the respondent (Rittippant et al.,
2009).The SMS-based survey is usually carried out in the form of single question per
SMS, which is normally in the form of “YES/NO or True/False etc.”. If a questionnaire
consists of multiple questions then the surveys is carried in multiple SMS i.e. ask another
SMS question when previous question is answered. Another major problem is
question/answer synchronization as it is difficult to synchronize the questions and its
answers with respondents in case of multiple questions contain in a survey. Maintaining
the order of questions is also a challenging task because in many cases the survey
questions are inter-dependent, so the correct order of question is necessary in this
situations. For this, the next question may be sent to a user if the previous one is
answered. But, there are possibilities of SMS delay due to SMS traffic in rush hours,
which may disturbs this order. Incomplete survey may also result as it is possible that a
user may respond to some SMS questions and ignore the rest. These incomplete surveys
and questionnaire generates fake reports. It should be noted that SMS is mostly used by
young and teenage users. Therefore, the data collected through SMS is not the actual
representation of the target population and represents a skewed distribution. The existing
SMS applications are not capable to handle the surveys based on multiple choice
questions.
4. Research Approach
The study reported in this research article was conducted using mixed mode surveys
consisting of both Paper-based and SMS-based. The population was M.Phil and PhD
faculty and scholars of the University of Peshawar. The reason for choosing this
population is that surveys and data collection is extensively used by research scholars
especially in Social Science departments. A random sample of 300 was selected from
research scholars at University of Peshawar. The population is round about 1000
(approximately). The ratio of the questionnaire were (200 Paper and 200 SMS= Total
400), in which some respondents were selected for both methods (Paper and SMS). The
respondents were asked to select “Like” one method of data collection that best suit their
needs or they used as research tool from the five well-known methods (mail, email, web,
mobile and SMS) along with their age. The responses were recorded as:
Paper-based responses: 150 (out of 200) mostly distributed/collected by hand.
SMS-based responses: 165 (out of 200)

4.1 Results and Discussion
Normally the ages of the research scholars and professors at the University of Peshawar
ranges from 23 to 61+ years. The age factor and responses in paper-based surveying were
recorded in table 4.

The above Table 4 and Figure 2 show that people in age group 23-45 (young peoples)
are more like to collected data using electronic technologies like e-mail, web, mobile and
SMS. The people in the age group 45-61+ years are more like to collect data using paper.
They are not comfortable with electronic technologies like email, web and mobiles.
However, this age group likes SMS as a data collection tool.

The t stat value lying in-between the t critical two tail values (-2.3646<0.4<2.3646) and
depicted in the Figure 4. Hence we accept the null hypothesis and conclude that there no
significant difference between the responses of email-based surveys and web-based
surveys. Both modes are internet dependent and restrict a lay man from responding
especially in developing countries.

SMS-based data collection is more dominant method of data collection. The figure.2
showed a skewed distribution as the young age group 23-to-45 has more tendency
towards electronic technologies like email, web, mobile and SMS. While people in age
group 54-60+ show more tendency towards paper and SMS. It means that SMS is more
dominant in all age group of peoples. The three methods namely email, web and mobile
browser-based application are internet dependent and are not liked by most of the
respondents.
The age factor and responses in SMS-based survey were recorded in Table 5. The five
methods of data collection liked by age groups were recorded.

Figure 3: The responses using SMS-based survey and age factor
The SMS-based data collection in table.5 shows that SMS is more liked by all age
groups.
Figure.3 shows that SMS is a dominant data collection method whereas mobile and
paper-based data collection is more popular as compare to email and Web-based surveys.
Paper-based data collection is more liked by the age group 54-61.
The responses collected using SMS-based mode in table.5 is tested using ANOVA test to
find the differences between the collected responses.
H0: There is no difference between the responses for all modes of data collection.
H0: µ1=µ2=µ3=µ4=µ5
H1: There is a difference between the responses for all modes of data collection.

The results for SMS-based data collection shows that F > F crit (33.57143>2.866081).
Hence we reject the null hypothesis and accept the alternative hypothesis as there is
difference between the responses.
The two Modes (paper-based and SMS-based) used for response collection also yields
interesting statistics by analysing the SMS columns in table.4 which is paper-based
collection and table.5 which is SMS-based collection. Here we use t-test for analysis of
columns of the table.4 and table.5.
H0: There is no difference between the responses collected using Paper mode and
SMS mode.
H1: There is a difference between the SMS mode and Paper mode.

that there is a difference between the SMS mode and Paper mode and hence proved from
our experiment.

The SMS-based data collection is dominant mode to target a specific population in low
budget projects. Also it is very fast mode in term of collecting data. In our experiment we
collected data in just four days while the paper-based took sixteen days in collection with
lots of physical efforts.
5. Conclusion and Recommendations
In this paper we described five modes of conducting surveys namely mail-based,
telephones-based, email-based, Web-based, and SMS-based. Based on related literature,
we can conclude that surveys conducted through traditional approach is time consuming
and costly. Telephone-based surveys are expensive, but almost real-time data collection
is possible on national and international level. The email-based surveys yield good
response rate but are suffering from spam/junk mail problems. The Web-based data
collection is an alternate approach to mail and email-based surveys with advantages of
low-cost and unlimited geographical boundaries. However, Web-based surveys are
suffering from low response rate due to limited internet coverage in developing countries.
SMS is widely used for surveys and data collection because of timely and good response
rates. From surveyor point of view it is quite difficult to manage a large survey using
SMS. This is because the ordinary SMS based survey consists of single question per SMS
or single SMS per question. Also, error rate of answering to SMS-based question is high
as compare to Web-forms. The current SMS-based surveys has limitations like single
question per SMS and missing of rich content like picture, audio and videos due to
limited characters capacity i.e. 140 bytes. Normally, in SMS-based data collection a
single question may be asked per SMS, which is not a best way to utilize their
capabilities. The internet coverage bias problem can be better managed using SMS
because SMS is GSM-based service and has more geographic coverage as compare to
Web. The mobile phone is pervasive device used by a huge number of people around the
globe. Although, user’s trends are now shifting towards smartphones and tablets in which
bundles of survey applications can be installed, but low-end mobile devices and SMS
cannot be underestimated due to extensive usage in developing countries. In order to
effectively used SMS for surveys and data collection, we recommend the following work
for future.

The usage of SMS must be utilized in a better way not only for surveys but for other data
collection needs like collecting student’s attendance and conducting quizzes in case of m-
learning scenario. The existing SMS applications and SMS-based surveys applications
are not suitable for surveys which are based on multiple questions. For example, in Web-
based the survey questions can be displayed in attractive format using the radio buttons,
list options, clear textboxes for open ended questions, rang-type questions, defaults
options, while in SMS-based surveys such representation of questionnaire is not
available. Therefore, we recommend the development of a better SMS-based survey
application for Smartphones, Tablets and J2ME-based phones which can possibly
represent a survey questionnaire in attractive format. This will help in SMS-based form
processing and will be able to handle surveys which are based on multiple-questions and
multiple-choice questions.
SMS has limited character capacity for sending and receiving of data, but better lossless
compression, assembling and dissembling techniques can enhance their usage, speed and
presentation.
We recommend an integrated and centralized survey application, which can handled both
Web and SMS-based surveys in an efficient and uniform ways using existing GSM
network or internet. This approach is necessary for building the trust of respondents and
for security and privacy of data. Because, the sensitive data of an organization cannot be
stored or recorded on third-party servers. The application should be installed and
maintained locally by the surveyor with provision of strong security and privacy for both
data and respondent.
