Psychometrics applies measurement theory to behavioral and cognitive processes, helping analysts develop self-report measures that assess intended concepts rather than merely collect answers. section 6.2.2
Effective psychometric practice includes:
- Using peer-reviewed, tested questionnaires as starting points instead of creating every measure from scratch. section 6.2.2
- Selecting wording and question order carefully because earlier questions can prime later responses. section 6.2.2
- Choosing a response scale and presentation format appropriate to the question and construct. section 6.2.2
Avoiding question-order bias
Ask how often respondents use a software feature before asking whether it improved usability; reversing the order may influence the second response. section 6.2.2
Figure 6.7 How do you think the wording of these questions might affect the responses you receive?
Compare how alternative question wording might affect the responses received. section 6.2.2
