Exhibit 13-4
In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five treatments (a total of 65 observations). The following information is provided.
SSTR = 200 (Sum Square Between Treatments)
SST = 800 (Total Sum Square)
-Refer to Exhibit 13-4. The mean square between treatments (MSTR) is
A)3.34
B)10.00
C)50.00
D)12.00

Question

Quizplus · Accepted Answer

The mean square between treatments (MSTR) is calculated by dividing the sum of squares between treatments (SSTR) by the degrees of freedom for treatments (k-1), where k is the number of treatments. Here, MSTR = SSTR / (k-1) = 200 / (5-1) = 50.00.
