Name an alternative to one-way ANOVA for independent groups (where ANOVA assumptions not met) ? Name an alternative to Repeated measures ANOVA?

What would be suitable follow-up tests to use instead of T-tests for each respectively?
To be used when your data does not meet ANOVA assumptions (e.g. not normally distributed and small sample)
Not as powerful as parametric tests
Based on 'ranked' data rather than means, so not skewed by extreme scores
Kruskal-Wallis: alternative to one-way ANOVA for independent groups
Friedman's ANOVA: alterative to RM ANOVA
Use pairwise comparisons to follow up if significant (reducing alpha level):
Mann-Whitney Tests - independent groups
Wilcoxon Test - related groups
