Below is the information for a completely randomized experimental design involving four treatments, where 12 observations were recorded for each treatment for a total of 48 observations.
SST = 210 (Sum of Squares Between Groups)
SS Total = 840 (Sum of Squares Total)
The computed value of F, or the test statistic, is _

Solution

df treatment=3

MST=(210/3)=70

SS within=840-210=630

df within=(48-4)=44

MS within=630/44

F=MST/MSwithin=(70)/(630/44)=4.88
