stats

three more questions for those who know their statistics:

-Compare the assumptions that must be met for the chi squared tests and ANOVA. Identify which test would use severely skewed data and why.

-Explain why the power of a test to discriminate between real and chance differences with very small effects increases with sample size using paramteric statistics, but not with non-parametric statistics.

-Explain why it is incorrect to perform a parametric test using ordinal data, and why a non-parametric test is preferable.
