Most research cannot test everyone. Instead a  sample  of the whole population is selected and tested. If this is done well, the results can be applied to the whole  population . This selection and testing of a sample is called  sampling .  If a  sample  is poorly chosen, all the data may be useless.  Sampling Population the group of people we wish to understand. Populations are often segmented by demographic or psychographic features (age, gender, interests, lifestyles). Sample a subset of the population that represents the whole group Respondents people who answer
Two Methods Sampling This relies on  available  people. For example, people passing in the street or walking through a mall.  This is not objective or representative. Thus, it is often  not scientific or reliable . Non-probability or Convenience Sampling   This is a sample selected  randomly  and according to scientific guidelines. To create a  simple random sample , you need (1) a list of the members of the population (2) a way to create random numbers.  Probability or Random Sampling

The Margin of Error  is the measure of accuracy of a survey.   The smaller the margin of error, the more accurate the survey.   Sampling Margin of Error What is your primary daily media channel? How accurate is this statistic? What is the margin of error?
Margin of Error = 1/ √ n x 100 n = number of respondents 48,804 people in TNS sample √ 48,804 = 220.916 1/221 = 0.0045 x 100 = 0.45% = 60.55% to 61.45%  Sampling Margin of Error What is your primary daily media channel? How accurate is this statistic? What is the margin of error?
41 respondents Margin of Error= 1/ √ n x 100 n = number of respondents 41  respondents √ 41 = 6.403124237432848686488 1/6.4 = 0.15625 x 100 = 15.6% margin of error √   25 = 5 1/5 = 0.2 X 100 = 20% margin of error How accurate is this statistic? What is the margin of error?   21.4% to  52.6%  consider themselves unfriendly to the environment Margin of Error= 1/ √ n x 100 n = number of respondents What would the margin of error be for 25 respondents?
Planning a survey Ask yourself the following 3 questions: WHO  will be the respondents? WHAT  information do you want to  learn from them? HOW  can you effectively get that information? Start-up questions
Planning a survey WHO  will be the respondents? Select respondents relevant to your focus Eg:  Ask  computer hardware  related q’s to hardware engineers / IT professionals Ask  toy  related questions to children and mothers Start-up  questions
Planning a survey WHAT  information do you want to  learn from them? Think clearly of your focus Think clearly of what the results might  look like Be specific Start-up  questions
Planning a survey Be specific Example: This research is done to ascertain the: -  Awareness  of /  knowledge  of -  Attitude  towards /  perception  of -  Demand  for etc Start-up  questions
Planning a survey HOW  can you effectively get that information? Choose effective questions Decide on type of survey  (mail, interview, telephone, online) Decide on response categories Design layout Decide on target population Decide on sample size Select sample Start-up  questions
Planning a survey Online Surveys Advantages  of online surveys: Access to a large number of people,  Quick Disadvantages  of online surveys: You cannot control the conditions   - someone else may answer   - not physically there to clarify or probe further Start-up  questions
The Questions Asking questions Avoid jargon, slang, abbreviations Avoid ambiguity, confusion and vagueness Avoid writing double-barreled questions Avoid leading  Avoid treating a respondent’s belief  about a hypothesis as a test of the hypothesis Start-up  questions
The Questions Asking questions 1. Avoid jargon, slang, abbreviations Example: How often do you use Polyethylene carriers? Ask instead: How often do you use plastic bags? Start-up  questions
The Questions Asking questions 2. Avoid ambiguity, confusion and vagueness Example: Do you eat out often? Ask instead: In a typical week, about how many meals do  you eat away from home, at a restaurant, cafeteria, or other eating establishment? Start-up  questions
The Questions Asking questions 3. Avoid Double-barreled questions Example: Do you support or oppose the use of lead  in lipsticks and paint? Ask instead: Do you support the use of lead in lipsticks? Do you support the use of lead in paint? Start-up  questions
The Questions Asking questions 4. Avoid Leading Example: Do you help the environment by using  canvas shopping bags? Ask instead: Do you use canvas shopping bags? Start-up  questions
The Questions Asking questions 5. Beliefs as real Example: Do you think more educated people wear  fur clothing? Ask instead: What is your education level? Do you wear fur clothing? Start-up  questions
The Questions Organising questions Question types: Closed – Likert scales   Semantic scales   Ranking scales Structured questions  (age, income, education level, etc) Open – Opinion Overall / final comments Start-up  questions
The Introduction [Fashion and the Environment] We are a team of  [Fashion Marketing]  students from Raffles College of Higher Education.  We are conducting this survey as part of our research project for our Academic Research and Communication Skills module under our lecturer and research supervisor Kavita Parwani.  The questionnaire should take about 5 minutes to complete.  Our research project examines  [the attitudes of the students of Raffles College of Higher Education towards the reuse, reduction and recycling of clothing.]  We hope that your response will help us understand our subject in greater depth.  The information we gather is confidential and anonymous, in other words, we will not name you or identify you in connection with the information you provide.  If you have any questions about the survey or our research project, please feel free to contact me,  [Josephine Lim, at josephinelim@gmail.com]  or our supervisor Kavita Parwani at kavitaparwani@raffles-college.edu.sg
