Hi,

I am struggling to find any guidance on how to conduct a power analysis in order to calculate sample size for MANCOVA.

- My design is 2x2 between subjects (male/female x 2-level experimental condition)

- I have 2 continuous DV's (questionnaires) (each also has 2 sub-scales so potentially 4 DV's)

- I have 5 covariates (demographics: age, ethnicity, socio-economic status etc.)

Any help appreciated,

Thanks,

Joe
