Question
The following ANOVA table is from an experiment that had a control group receiving a placebo as the no treatment control, a group that received a dose of experimental compound A, another group receiving compound B. Each of the groups contained 6 subjects. The following information has been calculated but important pieces are missing.
Given the above table calculate the mean squares column.
Source of Variation Sum of Squares df Mean squares F-ratio P Groups (treatments) 8.804 2 0.004 Error 10.515 15 Total 18.516 17Explanation / Answer
Mean Square = Sum of Square/DF
MST = SST/DFT = 8.804/2 = 4.402
MSE = SSE/DFT = 10.515/15 = 0.701
F-ratio = MST/MSE = 4.402/0.701 = 6.2796
