  1. Data Collection Sabrina 9810002M Zooey 9810003M

  2. I. The use of data • To know what certain people are thinking or doing by asking them or observing them. • Quantitative data collection: Use questionnaires to show numbers . • Qualitative data collection: Use personal interview to show detail information.

  3. II. The focus of enquiry • Primary data: Data researchers collect by themselves is to serve researchers’ specific purpose. • Secondary data: Data collected by others comes from a variety of sources. • The group of interest is defined as the population. • A sample is a selection from the population of interest. • More different population larger sample

  4. III. Asking questions • A questionnaire is a tool used to ask questions which is in a variety of ways, like email, postal and telephone surveys and structured and semi-structured interviews. • Structured interview = closed questions = answer predetermined items. • Semi-structured interview = open-ended questions = answer in own words.

  5. Questions Open Closed Classifica -tional Lists Ranking Scale

  6. Classificational questions: The inquirer may be interested in gender, age, marital status and occupation (personal information). Ex: Age last birthday? □ Under 18 □ 18-25 □ 26-30 □ 31-40 □ 41-50

  7. List questions: To ask the participant to select one or more from a given list of alternatives. Ex: Which are your favorite games in class? □ Simon Says □ Mime □ Dodge ball □ Car Racing □ Snake

  8. Ranking questions: To ask a respondent to give an order or preference. Ex: Rank the following factors in order of level when deciding the source of pressure. (from 5 the highest to 1 the lowest) □ peer pressure □ exams □ parents’ expectation □ pressure from teacher □ homework

  9. Scale (rating) questions: To determine the strength of views or opinions. Ex: How likely do you like (agree) to play games? □ Very likely (Agree strongly) 5 □ Quite likely (Agree slightly) 4 □ Neither likely (Agree) nor unlikely (Disagree) 3 □ Quite unlikely (Disagree slightly) 2 □ Very unlikely (Disagree strongly) 1

  10. IV. Framing questions • Avoid bias and leading questions. Ex: “ Would you agree that…” • Avoid jargon or shorthand. Ex: “Would you like to use CALL…” • Avoid ambiguous words. Ex: usually, recently, frequently…

  11. Keep questions short and simple. Avoid long questions. Ex: “Given the recent change in price and the fall in demand usually experienced at this time of year, do you think a 20 pence promotional voucher would…” • Avoid questions with negatives. Ex: “ Do you never…”

  12. Avoid hypothetical questions. Ex: “ If you were a millionaire, would you…” • Use filters to avoid irrelevant questions. Ex: “ If a smoker jump to question 3…” • Make it easy for respondent to answer the questions. Ex: “ What did you buy in the last week?” ※ In general it’s easier to use or improve existing questions.

  13. V. Qualitative Data Collection: Collect data by interviewing and conducted individually or in a group. • 1. Focus group interviews: Fewer than 10 questions • 2. Open-ended questions: Allow more self-reflections • 3. Avoid using “why” questions: Use “how come” or “ what” • 4. Carefully develop the questions by doing pilot testing

  14. 5. Provide enough information for understanding • 6. Arrange questions from general to specific • 7. Listen more, talk less, and ask ”real questions” (the interviewer doesn’t already know or anticipate the response) • 8. Try to get “ inner voice” instead of “ superficial” information • 9. Take notes and bring tape-recording: Easy to transcribe

  15. 10. Ask questions when you do not understand: Ask for examples or concrete details • 11. Explore laughter, pauses, facial expressions • 12. Ask participants to tell a story: To get a complete picture (transcription mode1 and model 2) • 13. Follow your instincts : Try to feel participants’ feelings

  16. VI. Benefits of using a questionnaire in interviewing: • A. To ensure covering all of the questions • B. Can explore more in- depth information within each of the questions • C. Collect both quantitative and qualitative data altogether
