Likert scale

a type of survey question where respondents are asked to rate the level at which they agree or disagree with a given statement. For example:

I find this software easy to use.

A Likert scale is used to measure attitudes, preferences, and subjective reactions. In software evaluation, we can often objectively measure efficiency and effectiveness with performance metrics such as time taken or errors made. Likert scales and other attitudinal scales help get at the emotional and preferential responses people have to the design. Is it attractive, fun, professional, easy?
