2 Tailed or 1 Tailed

Easy question…and it’s probably been discussed before. But can anyone explain to me when you you the two tailed t-test or the one tailed? For some reason this is just not sinking in…

When you want to test an equality, it’s a two tail When you test the condition “b0 above 1” or “b0 below 1” it’s a one tail

With the exception of the F-test which is always one-tail T/G

pre- july 7 it’s no tail… post… hopefully more :slight_smile: … I’m in the middle of mock 2 right now- that explains the immature comments

BP test is also only 1 tail

chai 2 is one tailed
