Hello Everyone ,
Good day ,
I was trying out Bluesky yesterday and I couldn't get the p-value for a hypothesis test. 2 sample t-test, Independent , to be precise. Any idea ?
Thank you

The independent samples t-test first does an F test on the equality of variances. The p-value for that is labeled “Sig.” You can use that test to choose which of the two t-tests to use. If the F is not significant (i.e. larger than 0.05), you would look at the top t-test for “Equal variances assumed” and its p-value labeled “Sig.(2-tailed).” If the F is significant, then you would choose the bottom t-test labeled “Equal variances not assumed” and it’s p-value, also labeled “Sig(2-tailed).”
An alternative approach is to never assume the variances are equal and so always choose the bottom t-test.
For t-test paired samples look at the column p-value.
For t-test one sample look at the column Sig.(2-tail).
Oh and I went to Analysis -> Means -> T-test , Independent Samples.
