- Planning for the Use of Questionnaires
- The people you need to question are widely dispersed
- A large number of people involved in the systems project, and it is meaningful to know what proportion of a given group approves / disapproves of a particular feature of the proposed system.
- You are doing an exploratory study and want to gauge overall opinion before the systems project is given any specific direction.
- You wish to be certain that any problems with the current system are identified and addressed in follow-up interviews.
- Writing Questions
- Open-Ended Questions
- Closed Questions
- Using Scales in Questionnaires
- Scaling Fundamentals
- Reasons for Scaling
- to measure the attitudes or characteristics of the people answering the questions
- to have the respondents judge the subject of the questionnaire
- Measurement
- Nominal - used to classify things
- Ordinal - used for classification with rank ordering
- Interval - intervals between each of the numbers are equal
- Ratio - intervals are equal and there is an absolute zero
- Validity and Reliability (consistency)
- Constructing Scales
- Leniency (respondents are easy raters) - move scale
- Central tendency (respondents rate everything as average) - increase # of points on scale
- Halo effect (impressions formed in one question influence answers on other questions) - rearrange questions
- Designing and Administering Questionnaires
- Designing the Questionnaire
- Questionnaire Format
- allow ample white space
- allow adequate space for responses

- Employ respondents' associated tendencies
- Bring up less controversial items first
