In an independent measures experiment with three treatment c

In an independent measures experiment with three treatment conditions, all three treatments have the same mean, x-bar₁ = x-bar₂ = x-bar₃. For these data, what is SS_between :

a. 0

b. 1

c. 3(5.50)

d. cannot be determined without additional information

Solution

As the observations are not given, so one cannot find SS_between. Therefore, additional information is required for determining the SS_between.

Hence, option (d) is correct.
