NOT comparisons involve comparing a specific language set against all the others in a particular project. They are commonly used when a project involves more than two language sets as a way of identifying what makes a particular language set unique in comparison to all of the others grouped together.

A NOT comparison is constructed as [X] vs [NOT X].

Consider what this would look like in a scenario where you have four language sets to analyse:

  • [A] vs [B+C+D]
  • [B] vs [A+C+D]
  • [C] vs [A+B+D]
  • [D] vs [A+B+C]

NOT comparisons in practice

This approach can be useful whenever you are working with more than two language sets. Some common examples include:

  • Analysing one brand against a group of competitors
  • Isolating a particular demographic group (e.g. age group, geographic group) and comparing against all others
  • Comparing NPS responses from promoters against detractors and neutrals

How to create a NOT comparison

  1. Navigate to the Data Library
  2. Hover over the single language set you want to isolate from the others
  3. Click the Venn diagram icon to 'Compare to all others'
  4. You will be brought to a preview of the comparison. Click 'Save' if it is what you are looking for.
  5. The combined language set will be saved within your Data Library using the format 'NOT xxxxx', and can be used in other comparisons as needed.

To ensure no duplication of data when creating additional NOT comparisons, any NOT language sets created previously will be excluded.
