Today in class we started our coverage of chi-squared testing. With chi-squared models we have three different tests we can run (1) Goodness of Fit, (2) Homogeneity and (3) Independence. It is important to note that chi-square tests can only be used when the data is in counts. Also we only do hypothesis tests for chi-squared tests. We only covered goodness of fit tests in class, the other two tests are up to you to cover over break. If you have questions with the other two tests come talk to me.
Because we are getting close to the AP exam. The classes after break will be dedicated to reviewing for the exam.
