Measurement – Clarity of of Questions

Survey questions must be unambiguous. Poorly worded questions require the respondents to interpret the meaning. In essence, this has respondents answering different questions. Questions which have high responses, at either end of the scale, should be reviewed. If the extremes indicate problems the rest of the questions should also be reviewed.

The table below presents three questions with multiple interpretations. Each interpretation would lead to a different response.
