I used a filter to extract only two values of a variable:
Gender = 'female' or Gender ='male'
When I try to run a t-test, I get the message:
"Grouping variable 'Gender' must have only two values"

What am I doing wrong?

Hey @Doethwr,

It does not work like this:
Gender = 'female' or Gender = 'male'

a possible filter could be this:
Gender == 'female' or Gender == 'male'

Cheers,
