Hello Alberto,
It depends what type of power analysis you mean: a priori or post hoc...
For a priori power analysis, you'd also need:
For post hoc analysis:
Regarding 5 DVs:
So overall I'd recommend (a) a priori power analysis to calculate sample size, and (b) a univariate DV. Pursuit of post hoc and/or power analysis for multivariate 1D DVs may require theoretical development and validation.

Hello Professor Pataky,
I want to estimate the statistical power of my data. I have 2 samples with 9 subjects each, and 5 dependent variables (5 joint angles). In this case, What is the procedure to estimate the statistical power1d for these data sets?
Also, since I have 5 DV, Should I test for only one of them or all 5?
Thank you in advance, -Alberto Sanchez
