Reference no: EM13791839

The data below are from an independent-measures experiment comparing three different treatment conditions.

Treatment 1         Treatment 2         Treatment 3

0                            1                            6

1                            4                            5

0                            1                            8

3                            2                            5

a. use an analysis of variance with α = .05 to determine whether these data indicate any significant mean differences among the treatments.

b. Compute η2 , the percentage of variance accounted for by the treatment.

c. use the Tukey's HSD test to determine which of the treatments are significantly different from each other. Use the .05 level of significance for all tests.
