How to use it?
Below you can find a step-wise approach how to approach your data finding with questionnaire.
Step 1: Determine what information you would like to obtain.
Step 2: Decide what is the audience for your questionnaire
Step 3: Decide on data collection method (electronic, phone, postal)
Step 4: Decide on types of questions
Step 5: Pilot the questionnaire on a sample of potential respondents and revise questions if necessary
Step 6: Distribute the questionnaire
Step 7: Chase non-respondents
Step 8: Analyse the responses
Step 9: Present and use the findings
- Keep the questionnaire as short as possible – don’t bore or frustrate the respondent
- Have an underlying reason for every question
- Group topic areas together to keep the respondent focused
- It is not a trivial task to create good questions, take time and test them upfront with a small group of respondents.
Advantages and disadvantages:
- The responses are gathered in a standardised way.
- Information can be collected in short period of time from a large number of people, often geographically dispersed.
- Inexpensive way to reach a large number of people.
- Standard questionnaire providers quantifiable answers to a research.
- Questionnaires allow respondents to take time to consider their responses carefully without interferences from others, e.g. interviewer.
- They permit anonymity.
- There is no way to check how truthful a respondent is being
- It is quite difficult to create unambiguous questions. There is no possibility to explain questions, so they may be misinterpreted and as consequence incorrectly completed. You shall test your questionnaire on a small group of respondents first to ensure it works as you designed it, before sending it around.
- Low response rate, if not administered. To increase response rate, an incentive is offered: “You have chance to win an iPod” kind of statements.
- Questionnaires are not suitable to investigate long, complex issues.
