Exclude data from a T-test
Posted: Tue Jul 10, 2018 2:12 pm
Hi
I have a response (exam results) for a a range of schools over 3 years.
Running ANOVA works a treat for Response VS Year (3 levels).
I would like to demonstrate running T-tests for the same response for a subeset of the years -- ie I want to exclude a year from the analysis. Currently this is not possible and I would need to edit the data.
is there any way to filter the data OR to exclude a level from the T-test...?
Cheers
