Re: Levene-Test for related samples?

From David Howell's Stat Text.

 t = [(F-1)*Sqrt(n-2)]/[(2*Sqrt(F(1-r squared)))].

HTH,

df for this t is n-2.
F = largest variance divided by the smallest variance
r = correlation between the matched or pair scors.
Check t for sign. If it is not significant than you can safely conclude
that you have met the equal variances assumption for the dependent t
-test.

Dear List,

I want to compare the variances of two related samples, but i don't
know the statistical test to do this job. In other Words, I'm looking
for a Levene-Test for dependent samples. Could someone tell me the
solution? I couldn't find an answer in my statistic books.

Thanks all,

Michael
