There are some issues you should keep in mind when using the Chi-squared test. Sometimes not all assumptions underlying the test are met, while in other cases there are more powerful tests you can…

This video explains how the Chi-squared test for goodness of fit works. You use it to compare an observed frequency distribution with an expected frequency distribution based on theory.

You can use the Chi-squared test to assess the independence between two categorical variables, but by itself it tells you nothing beyond this. In this video Emiel takes the interpretation of the…

This video explains the Chi-squared test for independence using the observed and expected values.

If you want to describe the relation between two categorical variables, you can summarize the observed frequencies in a contingency table. These frequencies can be interpreted as joint, marginal and…
