The following data summarize the results from an independent-measures study comparing three treatment conditions. Treatment I II III N = 12 3 5 6 G = 60 5 5 10 ∑X2 = 392 3 1 10 1 5 6 x̅1 = 3 x̅2 = 4 x̅3 = 8 T1 = 12 T2 = 16 T3 =32 SS1 = 8 SS2 = 12 SS3 = 16 Use an ANOVA with α = .05 to determine whether there are any significant differences among the three treatment means. Compute the test statistic (Must also show work for SS, df, and MS values) Based on the calculated test statistic, would you reject the null hypothesis? Based on the previously conducted steps, we can conclude what?
