Question
41+ A researcher found significant differences in the mean running speeds of sprinters wearing shoes made by Nike, Reebok, and Adidas using an analysis of variance. The 
2 calculated on the basis of group membership (based on which shoes were worn) equaled .16. The value of 2 shows that
a) the r value would be .4.
b) 84% of the variability in running speed is attributed to shoe brand.
c) 16% of the variability in running speed is attributed to shoe brand.
d) most of the factors influencing running speed are contained in the brand of shoes worn by runners.
