The NIH wants to compare the mean weight loss for five different diets. They measure the weight loss (in pounds) of 5 men assigned to each of the diets for one month. The resulting data set is below.
Diet 1,Diet 2,Diet 3,Diet 4,Diet 5
-0.5,1.3,-1.2,-1.2,-1.1
0.4,-0.2,0,-1.4,0.7
0.7,-0.8,0.4,-1.2,0.2
-0.9,0.9,-0.8,-2.5,-1.3
0.7,-0.3,-1.6,-1,0.3
1. Which of the following is NOT an assumption that should be checked before performing an ANOVA?
a. The variability in weight loss should be roughly the same for each diet.
b. The average weight loss should be roughly the same for each diet.
c. Weight loss should be roughly normally distributed for each diet.
2. What is the F statistic for the ANOVA?
