Question

Texts: The following data were obtained from an independent-measures research study comparing three treatment conditions. Use an ANOVA with a = 0.05 to determine whether there are any significant mean differences among the treatments (do ALL the steps of a hypothesis test). If so, solve for the effect size and conduct post-hoc tests. Treatment 1. 2. 3. Columns 5 2 7 1 6 3 2 2 2 3 3 4 0 5 5 1 3 2 2 0 4 2 3 5 T1 = ? T2 = ? T3 = ? SS1 = ? SS2 = ?
