Answer
The correct answer is - A
It is given in the question that the researcher reports an F-ratio with df = 2, 18 from an independent-measures research study. Based on the df values, there will be 3 (three) treatments compared in the study, and the total number of subjects participating in the study would be 21.

1. The following data represent the results from an independent-measures experiment comparing three treatment conditions. Use an analysis of variance with α = .05 to determine whether these data are sufficient to conclude that there are significant differences between the treatments. You do not need to do post-hoc tests. Treatments 1 2 3 2 6 6 N = 12 4 6 10 G = 60 2 2 10 ∑X2 = 408 0 6 6 T = 8 T = 20 T = 32 SS = 8 SS = 12 SS = 16 2. A researcher reports an F-ratio with df =...
