# MANCOVA: 8 levels and 3 dependent variables

Large Effect Size

Power analysis for a MANCOVA with eight levels and three dependent variables was conducted in G-POWER to determine a sufficient sample size using an alpha of 0.05, a power of 0.80, and a large effect size (f2 = 0.40) (Faul et al., 2008). Based on the aforementioned assumptions, the desired sample size is 24.

Medium Effect Size

Power analysis for a MANCOVA with eight levels and three dependent variables was conducted in G-POWER to determine a sufficient sample size using an alpha of 0.05, a power of 0.80, and a medium effect size (f2 = 0.25) (Faul et al., 2008). Based on the aforementioned assumptions, the desired sample size is 40.

Small Effect Size

Power analysis for a MANCOVA with eight levels and three dependent variables was conducted in G-POWER to determine a sufficient sample size using an alpha of 0.05, a power of 0.80, and a small effect size (f2 = 0.10) (Faul et al., 2008). Based on the aforementioned assumptions, the desired sample size is 80.
