Chapter 11, Chi-Square Tests and Nonparametric Tests

So much content of lecture and such rapid instruction for me. Notwithstanding, the good practice on retention in memory may write them down on my blog, not to show myself off at all.

1. Overview on last lecture about mean and proportion, either independent and dependent two samples. With more than 2 samples, Chi-square is a possible solution to test the null hypothesis. The exceptions of using Chi-Square include Less Groups, Significant Sample Size on each group, and selective-group or merging groups that result in distinct a consequence.
2. Types of Chi-Square, GOF, Homogeneities, and Independency. ( No details yet ;) )
