Create new variable(s) that show the respondents who selected the top 2 options

This QScript creates new variables that show the proportion of respondents who selected the top 2 options in Pick One and Pick One - Multi questionsNominal, Nominal - Multi, Ordinal or Ordinal - Multi variable sets (i.e., it computes what is commonly referred to as 'Top 2 Box' scores). Categories which look like Don't Know options will not be included in the top boxes, and when such categories are identified the script will give you the option to remove them.

Example

The table on the left shows a SUMMARY table of a Pick One - Multi questionNominal - Multi variable set. The table on the right shows a SUMMARY of the Pick Any questionBinary - Multi variable set created by this QScript. Note that the computation is performed prior to rounding, which is why the calculation does not appear to add up correctly.

Technical details

The top options are identified by looking at the numeric Value for each category that is not selected as Missing Data in the Values, and choosing the highest. The script will:

  1. Ask you if you want to consider questionsvariable sets whose categories suggest that they may be scale questionsvariable sets (for example, 5-point agreement scales).
  2. Ask you to select which questionsvariable sets to generate new variables for.
  3. Give you the option to remove categories which look like Don't Know options. This is equivalent to setting the category as Missing Data.
  4. Create new variables for the top 2 categories of each selected questionvariable set.

# Produce a new folder in your report showing the new questionsvariable sets.
