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
G

Got it - worked a treat.

Define the filter (to remove the levels I dont want)
Run the T-test.

Love it.
