Hello listers,
Anyone quick at calculating required sample sizes? Annoying government
worksite restrictions are blocking me from downloading power software
like G*Power.
I am after the required sample size for detecting a -large effect at 80%
power and alpha level of .05 for a 2x2x2 ANOVA with unequal cells. Can
anyone give me the required sample size and indicate which program they
used so I have a reference?
Regards,
Hunna
