“As a matter of fact, ANOVA and the Kruskal-Wallace test are both for situations where groups being compared are not related, the more commonly encountered situation. If the groups are related, then we should use repeated measure ANOVA instead of the ordinary ANOVA discussed in this book, and the Friedman test instead of the Kruskal-Wallis test. These tests are not usually covered in basic statistics books.”

“. . . no matter what statistical decisions we make about the null hypothesis, there is always a chance of error. This is understandable because we never know the absolute truth of the population-if we knew, there would be no need to do a statistical test. All we are doing in inferential statistics is to estimate the population based on a sample by employing knowledge of probability theory.”

#bookhaul from the last couple days 📚 The tagged is for my next grad school class. The other two were recently weeded from the library I work at.
