Hi,
can anyone tell me more about the Mauchly sphericity test?

Exact problem: I am using spss and the Mauchly sphericity test prints
out:
Mauchly-W = 0.000
approx-chi2 =  .
df = 9
significance =  .

Does this mean the within-subject factors fail to meet the assumption of
sphericity?
I guess yes, but I am not shure.

Thanks for your help,
Eike
