The following data represent the results from an independent-measures study comparing three treatments.
| Treatment | ||
| I | II | III |
| n = 13 | n = 13 | n = 13 |
| M = 3 | M = 3 | M = 7 |
| T = 39 | T = 39 | T = 91 |
(a) Compute SS for the set of 3 treatment means. (Use
the three means as a set of n = 3 scores and compute
SS.) (Use 1 decimal place.)
(b) Using the result from part (a), compute
n(SSmeans). Note that this value is
equal to SSbetween. (Use 1 decimal
place.)
(c) Now, compute SSbetween with the
computational formula using the T values. You should
obtain the same result as in part b. Use 1 decimal place.

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 (Hint: start by filling in the missing values on the table below). Be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all steps and all parts of all answers. Treatment 1 Treatment...
