Question:

Use n1, n2, 1, 2, .., s1, and s2 to calculate SSType (i. e., SSGroup), SSError, MSType, and MSE for the computer game study. Since the group for the computer game study is game type (the Type variable in the data set), we will use the more descriptive labels MSType, SSType, and dfType instead of MSGroup, SSGroup, and dfGroup. This is common practice and is similar to how statistical software reports results based on variable names.
