I have data that was gathered from the same people at two differing times. The distribution is normal. I want to do a paired t-test, but am not able to find out how to do a Levene test for the variances to see if the t-test is alright to do.
I know how to do it for non-paired t-tests, but that would require a grouping variable that I do not have because of my data.
Can you tell me where I can find the Levene test?
Thank you for your answer!
