What is a questionnaire?
- An instrument (form) to
- collect answers to questions
- collect factual data
- gathers information or measures
- A series of written questions/items in a fixed, rational order
Decisions in Questionnaire Design:
- What should be the title of my survey?
- How do I introduce my topic? Do I need a cover letter?
- What instructions do I provide the respondent?
- What should be asked?
- How should each question be phrased?
- In what sequence should the questions be arranged?
- What questionnaire layout will best serve the research objectives?
- How should the questionnaire be pretested?
- Does the questionnaire need to be revised?
What Should be Asked:
What to ask in questionnaire depends on:
1.The research problem definition/objectives
2.The communication medium to be used – E.g. some questions cannot be asked in personal interviews
- The type of statistical analysis to be performed – E.g. if you plan to do regression analysis, you may need to ask about, say, overall evaluations to use as dependent variable
- Questionnaire relevance
- ask only questions that are relevant to the research objective.
- Be careful not to leave out needed variables
- Don’t forget demographics and psychographics
- Questionnaire accuracy
- ask only questions that will provide accurate information.
- Information is reliable and valid.
- Question wording is critical to reduce error and increase accuracy.
