Question

Quizplus · Accepted Answer

The more scale points a scale has, the greater the potential discriminatory power it may have. This is because more scale points allow for more granularity and nuance in respondents' responses, enabling the scale to better capture a wider range of attitudes, experiences, and opinions. However, there is a limit to this, as having too many scale points can also lead to respondent fatigue, confusion, and a lack of differentiation between responses. Therefore, finding the optimal number of scale points depends on the research question, context, and population being studied.
