Changes to the report structure or data can affect significance test results.
Such changes include:
- Converting question types
- Adding and deleting questions
- Adding and deleting answers
- Applying filters
- Changing data settings
- Changing answer category totals
In most cases, when there are changes to the report structure or data, t-tests will be recalculated and significance test results will be updated automatically.
Any previous significance test results will be removed from the report
because t-tests cannot calculate changes resulting in:
- An unsupported question type to be used
- An answer category to contain 0% or 100%
- A subgroup to have less than 30 responses
- No variance between responses (all participants in a subgroup selected the same answer)
