Modify Data - Merge 10 Point Scales Into 3 Categories

This QScript creates merges the bottom 3, middle 4 and top 3 categories of 10-point scales.

Example

Technical details

This QScript:

Searches through all the questions in the project that contain 10 non-missing categories where the lowest scale point has a Value of 1 and the highest has 10.
Asks you if you want to consider questions whose categories suggest that they may be scale questions .
Warns you if any of your selected questions contain categories that look like 'Don't Know' options (and hence would likely not be useful to combine with the top k categories).
Merges the categories.
Produces a new folder in your Report showing which questions have been changed, and, if relevant, any problem questions.
