Usually if your questionnaire is designed to have questions summed into Question Categories --- that is, if individual Likert items are summed into Likert scales ---, then you wouldn't address the individual questions. x1 x2 In this post, I discuss how to use these instruments effectively, by looking into the difference between items and scales, and explaining how to analyse the data that they produce. Is there a proper earth ground point in this switch box? It is also possible to do factor analysis of Likert scale items, although some care must be taken.
