Set up an ANOVA type model and test for the presence of a difference in infections across
classrooms in the presence of weekday differences.
Questions 1-10 refer to this page:
Y
X =
1. The design is unbalanced?
2. The design is balanced?
3. The null hypothesis of equal classroom infections is rejected via a two way ANOVA?
4. Compute the SST
5. Compute the SSTr for classroom differences
6. Compute the SSTr for the weekday differences
7. Compute the observed f statistic
8. The critical f statistic at a = .05 for these numerator and denominator degrees of
freedom is less than the observed f statistics from these data?
9. Fisher's LSD identifies which weekday pairs as unequal? (not just a T/F question)
10. The within classroom variances are unequal?
