1. Imagine you’re the chair of the DPRC, and you want to know whether students who take a course with 3 different instructors score differently on the final exam.  Below is a spreadsheet with the final exam scores for five students in each of the 3 classes taught by different instructors. You need to complete the table below, and use the data from the completed table to compute each of the following:
    1. dfB
    1. dfW
      1. After computing Fobt, you must  review the ANOVA Critical Value Table (in weekly folder), and determine what Fcrit is. Compare Fobt to Fcrit, and state whether there is a statistically significant finding.
      1. If there is a significant finding, review the descriptive statistics and determine what order the groups are in.
      1. Write up the results of your ANOVA in APA format.
 95 98 92

 88 80 86
