Statistical power - Parametric vs Nonparametric test
See all my videos at:
https://www.tilestats.com/
In this video we will discuss the differences in statistical power and type 1 errors between the t-test and the Mann–Whitney U test (Wilcoxon Mann–Whitney (WMW), Wilcoxon rank-sum test)
1. Type 1 error - t-test vs WMW
2. Type 2 error - t-test vs WMW - normal distribution (04:30)
3. Type 2 error - t-test vs WMW - log-normal distribution (10:56)
4. R code for the simulations (12:12)
