  • Introductions Introductions
  • What is a survey? A “standardised” stimulus A measuring instrument
  • What is a survey? A way of converting “fuzzy stuff” into hard data for analysis
  • Purposes of survey research
    • Information gathering & describing
      • e.g., polls, attitudes, demographics
    • Theory-building & testing
      • Explanatory, e.g., why?
      • Predictive, e.g., what is likely to happen?
    • Often survey research does some of both.
  • Types of Surveys (Research Purposes) Descriptive
    • Collects basic descriptive data/statistics e.g., consumer profiles…(age, gender)
    Explanatory
    • Examine underlying data patterns
    • Linked to a hypothesis/research objective
  • Types of Surveys (Research Purposes) Predictive
    • What happens if…
    • Useful for marketing or assessing consumer behavior
    • Honours-MA-Ph.D survey research
  • Research Paradigms Phenomenological Positivist
    • Usually small # of participants
    • More about opinions & experiences
    • Focused on ethnographic style of research
    • Usually associated with qualitative data
    • Deductive
    • Seeks to explain causal relationships between variables
    • Usually uses quantitative data
    • Follows a structured approach or methodology
  • Quantitative Research Methods
    • Advantages
      • Larger sample sizes  greater confidence in results
      • Results can be representative of target population
      • Data can be readily summarised using computers
  • Quantitative Research Methods
    • Disadvantages
      • Impersonal (don’t get background context)
      • Large samples needed
      • Samples may not be representative
      • Cost and time involved
  • Types of Questionnaires Self - administered Interview - administered Postal questionnaire Delivery and collection questionnaire Telephone survey Face to face structured interview Web-based
  •  
  • Alreck and Settle (1995:26)
  • Questionnaire Planning/Design 1. Formulate Generic Questionnaire 2. Expand the Questionnaire Based on study objectives Turn into separate sections Question styles & types 3. Finalise Questionnaire -Pre-test/pilot test -Several drafts needed Placement & Funnel Qs
  • Formulate Generic Questionnaire
      • Turn objectives into sections of the survey
      • Ensure all questions relate to research objectives
      • For explanatory objectives or hypotheses ensure both dependent and independent variables exist
  • Cover Letter / Ethics Statement Outline details of research project
    • Purpose
    • What's involved?
    • Explain any risks/costs/rewards
    • Contact details
    • Human Ethics approval #
    • How is consent given/not give?
    • How to return?
    • Can choose not to continue anytime
  • Instructions
    • Provides consistency - helps to ensure standard conditions across different administrations
    • Explain how to do the survey in a user-friendly manner
    • Example: Life Effectiveness Questionnaire
  • Expanding the Survey
  • Screening
    • Does the participant qualify for the survey? (esp. for internet surveys)
    • Ask screening questions first, rather than later
    • Use branching if there are conditional questions
  • Flow/Structure
    • Logical order of questions (use sections)
    • Use funnel questions to move respondents through survey
    • Start off with easy to answer and engaging questions
    • More controversial questions in middle section
  • Personal Information
    • Put personal information at end of survey (if required), otherwise it may put off respondents
    • Consider response format e.g, Income in categories or ranges
  • Personal Information
    • More likely to respond to personal questions for anonymous or mail surveys as opposed to face to face or telephone
    • Show cards for responses may help for face to face interviews
  • Types of Questions Be able to justify and defend your choices ...
  • Types of Questions
  • Open-ended Questions
    • Rich information can be gathered
    • Useful for descriptive, exploratory work
    • Difficult and subjective to analyse
    • Time consuming
  • Closed-ended Questions
    • Important information may be lost forever
    • Useful for hypothesis testing
    • Easy and objective to analyse
    • Time-efficient
  • Open-ended Question Examples
    • What are the main issues you are currently facing in your life?
    • How many hours did you spend studying this week? _________
  • Closed-ended Question Types
    • Dichotomous questions
    • Multichotomous questions
    • The list (multiple response)
    • Ranking
    • Likert Scale
    • Graphical Scale
    • Semantic Differential
    • Non-verbal (Idiographic)
  • Dichotomous Simple Yes / No response e.g., Excluding this trip, have you visited Canberra in the previous five years? __ Yes __ No
  • Multichotomous More than two possible answers e.g., What type of attractions in your current trip to Canberra most appeal to you? __ historic buildings __ museum/art galleries __ parks and gardens
  • Multichotomous How many hours did you spend studying this week? __ less than 5 hours __ > 5 to 10 hours __ > 10 to 20 hours __ more than 20 hours
  • Frequency Scale Over the past month, how often have you argued with your intimate partner? 1. All the time 2. Fairly often 3. Occasionally 4. Never 5. Doesn’t apply to me at the moment
  • The List (Multiple Response) Provides a list of answers for respondents to choose from e.g., Tick any words or phrases that describe your perception of Canberra as a travel destination: __ Exciting __ Important __ Boring __ Enjoyable __ Interesting __ Historical
  • The List (Muliple-Response) What are the main issues you are currently facing in your life? (tick all that apply) __ financial __ physical/health __ academic __ employment/unemployment __ intimate relations __ social relations __ other (please specify)
  • Ranking Helps to measure the relative importance of several items Rank the importance of these reasons for taking a holiday to Canberra (from 1 (most) to 4 (least)): __ to visit friends and relatives __ for business __ for educational purposes __ for holiday/ sightseeing
  • Likert Scale Assesses differences of perceptions and allows measurement and comparison of these differences Indicate your degree of agreement with this statement: “ I am an adventurous person.” (circle the best response for you)
  • Graphical Rating Scale How would you rate your enjoyment of the movie you just saw? Mark with a cross (X) not enjoyable very enjoyable
  • Semantic Differential What is your view of smoking? Tick to show your opinion.

  • Non-verbal (Idiographic) Scale Point to the face that shows how you feel about what happened to the toy.
  • Sensitivity & Reliability
    • Scale should be sensitive yet reliable.
    • Watch out for too few or too many options
  • General aim: Maximise sensitivity (i.e. more options) Maximise reliability (i.e. less options) How many measurement options?
    • Minimum = 2
    • Average = 3 to 7
    • Maximum = 10?
    Scale of Measurement Guidelines
  • FEELING ABOUT SOMETHING EXTREMELY POSITIVE EXTREMELY NEGATIVE 2-Categories GOOD NOT GOOD 3-Categories GOOD FAIR POOR 4-Categories VERY GOOD GOOD FAIR POOR 5-Categories EXCELLENT VERY GOOD GOOD FAIR POOR
  • Watch out for too many or too few responses “ Capital punishment should be reintroduced for serious crimes” 1 = Agree 2 = Disagree 1 = Very, Very Strongly Agree 7 = Slightly Disagree 2 = Very Strongly Agree 8 = Disagree 3 = Strongly Agree 9 = Strongly Disagree 4 = Agree 10 = V. Strongly Disagree 5 = Slightly Agree 11 = V, V Strongly Disagree 6 = Neutral
  • Wording Questions
    • Does the question focus directly on the issue or topic to be measured? (If not, rewrite.)
    • Is the question stated as briefly as it can be? (If too long, restate it more briefly.)
  • Wording Questions
    • Is the question expressed as clearly and simply as it can be? I (f the meaning won’t be clear to every respondent, restructure the question.)
    • Use only core vocabulary - words and phrases people use in casual speech
  • Wording Questions
    • Limit the vocabulary so the least sophisticated respondent would be familiar with the words
    • Use simple sentences where possible and complex sentences only when actually required
    • Use two or more short, simple sentences rather than one compound or complex sentences
  • Finalise Questionnaire Draft
    • Questions need to be exhaustive and mutually exclusive
      • Include ‘other (please specify)’
      • Ensure categories do not overlap
  • Finalise Questionnaire Draft
    • Length
      • Try to keep them as short as possible
      • Only ask questions that relate to objectives
      • Tricks? Font size/double sided photocopying/numbering sections
  • Pre-testing and Pilot testing
    • Pre-test – try out on convenient others & revise
    • Pilot test – try out on a small sample from the target population & revise
    • Be assertive and interactive about seeking feedback – ask questions & observe
    • “The customer is always right.”
  • Maximising Response Rate
    • Layout and design is key
    • Respondent’s level of interest
    • Colour of paper
    • Accompanying letter / introduction
    • Mail surveys - self-addressed stamped return envelope
    • Rewards
    • Reminders or follow up calls
  • Examples
    • Examine the examples

  • Pre-test & Revise
    • Pre-test items and ask for feedback
    • Revise:
      • items which don’t apply to everybody
      • redundancy
      • skewed response items
      • misinterpreted items
      • non-completed items
    • Reconsider ordering & layout
  • Survey Format Checklist
    • Introduction/covering letter or verbal introducation
      • e.g. Who are you? Are you bona fide? Purpose of survey? Ethical approval? How results will be used? Confidentiality? Further info? Complaints?
    • Instructions
      • Sets the “mind frame”, but be aware few people will read it without good prompting and being easy-to-read
    • Group like questions together
    • Consider order effects, habituation, fatigue, switching between response formats
  • Survey Format
    • Font type / size, number of pages, margins, double vs. single-siding, colour, etc.
    • Demographics - single section, usually at beginning or end of questionnaire, only use relevant questions
    • Space for comments?
    • Ending the questionnaire – say thanks!
    • Pre-test the questionnaire & revise/refine
  • LUNCH BREAK
  • Survey Design Critique In pairs, look through the example questionnaires, and highlight aspects which:
    • could be improved
    • are particularly good
    • you would like to ask about
  • Implementing Surveys
  • Research Proposal
    • What are your study parameters?
    • When will you carry out the research?
    • How long will data collection last?
    • Who is your target population?
    • What are your time and cost constraints?
    • What research method will be used?
  • Types of Questionnaires Self - administered Interview - administered Postal questionnaire Delivery and collection questionnaire Telephone survey Face to face structured interview Web-based
  • Comparison of Data Collection Methods Alreck and Settle (1995:32)
  • Sampling
  • Sampling Terminology
    • Sampling Terminology
    • What is Sampling?
    • Sampling Techniques
    • Example: Shere Hite’s Sex Survey
    • Summary of Sampling Strategy
  • Sampling Terminology
    • Population
    • Sampling Frame
    • Sample
    • Representativeness
  • What is a sample?
    • A proportion of the research or survey population
    • Sample of a population being all ‘known cases’
  • Why sample?
    • Why sampling rather than a census?
    • Sampling reduces:
      • Cost, time, sample size and defines the research
      • If the sample is representative, allows inferences to be drawn concerning the total population
  • What is sampling? “ Sampling is the process of selecting units (e.g., people, organizations) from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen.” - Trochim, 2002
    • To generate a sample you need a sampling frame to select your sample from
    • List or database of all ‘known’ cases in a research population or study area (e.g., Canberra residents, Students at the University of Canberra, those staying in 5 star hotels in Sydney)
    Sampling frame
  • Sampling frame
    • The set of participants from which the sample is drawn
    • Examples:
        • Electoral Rolls
        • Membership Lists (organisations, graduates association)
        • Telephone Book
        • Members of Specific Groups or Clubs (Fishing, Ramblers)
        • Households or post codes
  • Sampling frame
    • What is the scope of your study? e.g.,
      • Local residents of Canberra over 18 or Canberra Households?
      • 5 Star hotel guests in last 5 years, 12 months, 2 weeks?
  • Sampling frame
    • Difficulties in identifying research population or finding a reasonable sampling frame e.g., ecstasy users
    • How accurate/up to date are lists or sample frames? Up to date? Are they missing members of the research population? e.g., Ph books
    • These issues impact on sampling and data collection techniques
  • Representativeness of sample depends on:
    • Adequacy of sampling frame
    • Selection strategy
    • Adequacy of sample size
    • Response rate – both the % & representativeness of people in sample who actually complete survey
    • Note: It is better to have a small, good sample than a large, poor sample.
  • Sampling Example: Shere Hite ‘American Sexology’
  • Male-Female Relations
    • Shere Hite ‘doyenne of sex polls’
    • Media furors & worldwide attention
    • 127-item questionnaire about marriage & relations between sexes
    • 4500 USA women, 14 to 85 years
    • Society and men need to change to improve lives of women
  • Some of Hite’s findings....
    • 70% married for 5 years having affairs...
    (usually more for ‘emotional closeness’ than sex)
    • 76% did not feel guilty
    • 87% had a closer female friend than husband
    • 98% wanted “basic changes” to love relationships
    • only 13% married for 2+years were still in love
    • 84% were emotionally unsatisfied
    • 95% reported emotional & psychological harassment from their men
  • Some of the critical comments....
    • “She goes in with prejudice & comes out with a statistic.”
    • “The survey often seems merely to provide an occasion for the author’s own male-bashing diatribes.”
    • “Hite uses statistics to bolster her opinion that American women are justifiably fed up with American men.”
  • Response rate & Selection bias - 1 100,000 questionnaires Sent to a variety of women’s groups - feminist organisations, church groups, garden clubs, etc. 4,500 replied (4.5% return rate)
  • “ We get pretty nervous if respondents in our survey go under 70%. Respondents to surveys differ from nonrespondents in one important way: they go to the trouble of filling out what in this case was a very long, complicated, and personal questionnaire.” - Regina Herzog, University of Michigan Institute for Social Research Response rate & Selection bias - 2
  • Sampling Techniques
    • Probability (random) sampling
      • Random
      • Systematic
      • Cluster
        • Multi-Stage Cluster
    • Non-probability sampling
      • Quota
      • Convenience
      • Snowball
  • Random/probability sampling
    • Each unit has an equal (and perhaps known) chance or probability of selection in the sample
    • Selection occurs entirely by random chance
    • Often called representative sampling
    • Simple random sampling
    • Everyone in the target population has an equal chance of selection
    • Useful if clear study area or population is identified
    • Similar to a lottery
    • List of names are assigned #s and randomly select #s of respondents
    • Randomly select # through table of random #s or by computer
    • Systematic random sampling
    • Selecting without first numbering
    • Respondents (units) selected from a list/file.
    • Useful when survey population is similar e.g. List of Students, List of Package Tourists
    • Select sample at regular intervals from the population e.g., every 5 th person on a list
    • Systematic random sampling
    • Cannot do 1 in every 5
    • As then 4 people out of 5 stand no chance of being selected
    • Select a random starting point between 1 and 5
    • Stratified Random Sampling
    • Sub-divide population into strata (e.g., by gender, age, or location)
    • Then random selection from within each stratum
    • Improves representativeness
    • e.g., Telephone interviews using post-code strata
    • Non-Random/Non-Probability
    • Also called purposive or judgemental sampling
    • Useful for exploratory research and case study research
    • Able to get large sample size quickly and useful when can’t find a sample frame
    • Non-Random/Non-Probability
    • Make assumptions and maybe generalisations from your data, but not on statistical grounds
    • Limitations include potential bias and applicability
    • Convenience Sampling
    • Sampling is by convenience rather than randomly
    • Due to time/financial constraints
    • e.g. surveying all those at a tourist attraction over one weekend
    • Purposive Sampling
    • Respondents selected for a particular purpose e.g., because they may be “typical” respondents
    • e.g., select sample of tourists aged 40-60 as this is the typical age group of visitors to Canberra
    • e.g., Frequent flyers to contact regarding service quality in an airline setting
  • Summary of sampling strategy
    • Identify target population and sampling frame
    • Selection sampling method
    • Calculate required sample size
    • Maximise return rate
    • Task
    A research project's aim is – “To identify the behaviour and attitudes of UC students with regard to its computing services”.
    • What is the research population?
    • How might you get hold of a sample frame?
    • What sampling technique would you use?
    • Confidence Levels / Margins of Error
    • Relates to representativeness of a sample of a target population - to what extent can we be confident about the results?
    • Gives the estimated range of values into which we expect other samples to fall say 95% of the time
    • Social sciences = at least 90% or above, preferably 95%
    • Example 95% Confidence Level Graphs
    • Example 95% Confidence Level Table
    • Confidence Level Example
    Survey of visitors to Canberra between June 1 - August 31, 2004 = 10,000 visitors Want to work with 95% confidence level and 3% margin of error How many to survey? Answer: Sample size = 964 people Q: What are your favourite attractions?
    • Following Results
    + / - 3% error @ 95% confidence level
    • Confidence Intervals / Margins of Error
    • One time out of 20, we expect the answers may be greater than +/- 3%
      • Establish the confidence level, margin of error you want to work with
      • Identify the number of surveys to be done
      • Once you have completed that number, do not do any additional surveys
    HOWEVER….
    • Confidence Intervals / Margins of Error
    • Sometimes we do surveys and we do not know how many will be returned until later, as with postal surveys
    • Thus you have to calculate the margin of error afterwards….
      • Count up # of returned surveys
      • Identify target population and confidence level
      • Calculate margin of error
    • Confidence Intervals / Margins of Error
    • All this assumes you know your target population and can get a sample frame
      • If not, a non-random sampling technique is best
    • Also consider whether you want to report results for sub-groups – the margins of error will be wider
      • Consider stratified random sampling
