T test output

Postby sunny_sun » Mon Apr 30, 2012 8:31 pm

Hy, at a T test output I obtained this: F = 0.015, p = 0.90, t = -3.77 and p = .000. Can I say that this is statistically significant?

The first F statistics and the p value (0.9) is for another test called Levene's test for equality of variances. It just tells you if you should read the first row of the t-test (next column to the right) or the second row.

The t statistics and its p (<0.0005) are the results for t-test. In this case the means are significantly different from each other because the p is less than the conventional cut point which is 0.05.

For how to better interpret the pieces, see this:
