Week 5
In this week we are going to discuss a last subject for non continuous data, that is, multinomial data and the multinomial distribution. The Chi squared test is a central test for discrete data types and can be used for inferential testing. Further, we are going to deal with the notion of power, that is; if there truly is a difference, how likely is it that the statistical tests will find it?
