Let’s look at some other factors that might influence pay – education(degree) and performance ratings. |

Last week, we found that average performance ratings do not differ between males and females in the population. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Now we need to see if they differ among the grades. Is the average performace rating the same for all grades? |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
(Assume variances are equal across the grades for this ANOVA.) |
|
You can use these columns to place grade Perf Ratings if desired. |
