The following data were obtained from an independent-measures research study comparing three treatment conditions.

I

II

III

n = 6

n = 4

n = 4                   

M = 2

M = 2.5

M = 5

N = 14

T = 12

T = 10

T = 20

G = 42

SS = 14

SS = 9

SS = 10

ΣX2tot = 182


Use an ANOVA with α = .05 to determine whether there are any significant mean differences among the treatments.

The following scores are from an independent-measures study comparing two treatment conditions. (Be sure to include your critical values) a. Use an independent -measures t-test with a = 0.05 to determine whether there is a significant mean difference between the two treatments. b. Use an ANOVA with a = 0.05 to determine whether there is a significant mean difference between the two treatments. You should find that F = t2. Treatment I Treatment II 10 7 N = 16 8...
