Problem
Three data sets have the following statistics:
Set D: mean = 40, standard deviation = 6
Set E: mean = 45, standard deviation = 6
Set F: mean = 43, standard deviation = 4
Rank the sets from most consistent to least consistent. (In case of equal standard deviation, treat the set with the lower mean as more consistent.)
(a) D, F, E
(b) F, E, D
(c) F, D, E
(d) D, E, F
