L e arning Out c om e s 3. The worlds most famous newspaper error President Harry Truman against Thomas Dewey Chicago Tribute prepared an incorrect headline without first getting accurate information Reason? bias inaccurate opinion polls Sampling 4. Most research cannot test everyone. Instead asampleof the whole population is selected and tested. If this is done well, the results can be applied to the wholepopulation . This selection and testing of a sample is calledsampling .If asampleis 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 5. Two Methods Sampling This relies onavailablepeople. For example, people passing in the street or walking through a mall.This is not objective or representative. Thus, it is oftennot scientific or reliable . Non-probability or Convenience Sampling This is a sample selectedrandomlyand according to scientific guidelines. To create asimple random sample , you need (1) a list of the members of the population (2) a way to create random numbers.Probability or Random Sampling 6. Sampling Lists and Random Numbers 7. 8. The Margin of Erroris 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? 9. 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? 10. 41 respondents Margin of Error= 1/ n x 100 n = number of respondents 41respondents 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% to52.6%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? 11. Planning a survey

• Ask yourself the following 3 questions:
• WHOwill be the respondents?
• WHATinformation do you want to
• learn from them?
• HOWcan you effectively get that
• information?

Start-up questions 12. Planning a survey WHOwill be the respondents? Select respondents relevant to your focus Eg:Askcomputer hardwarerelated qs to hardware engineers / IT professionals Asktoyrelated questions to children and mothers Start-upquestions 13. Planning a survey

• WHATinformation do you want to
• learn from them?
• Think clearly of your focus
• Think clearly of what the results mightlook like
• Be specific

Start-upquestions 14. Planning a survey Be specific Example: This research is done to ascertain the: -Awarenessof /knowledgeof -Attitudetowards /perceptionof -Demandfor etc Start-upquestions 15. Planning a survey

• HOWcan 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-upquestions 16. Planning a survey

• Online Surveys
• Quick
• You cannot control the conditions
• - someone else may answer
• - not physically there to clarify or probe further

Start-upquestions 17. The Questions

• Avoid jargon, slang, abbreviations
• Avoid ambiguity, confusion and vagueness
• Avoid writing double-barreled questions
• Avoid treating a respondents beliefabout a hypothesis as a test of the hypothesis

• Organising questions
• Question types:
• Closed
• Likert scales
• Semantic scales
• Ranking scales
• Structured questions(age, income, education level, etc)
• Open
• Opinion
