The following data were obtained from a repeated-measures study comparing 3 treatment conditions. Use a repeated-measures ANOVA with a=.05 to determine whether there are significant mean differences among the three treatments (do all 4 steps of conducting a hypothesis test!!):

Person	Treatment 1	Treatment 2	Treatment 3	Person Totals
A	0	2	4	P=6	N=15
B	0	3	6	P=9	G=60
C	3	7	8	P=18
D	0	7	5	P=12
E	2	6	7	P=15
	M=1	M=5	M=6
	T=5	T=25	T=30
	SS=8	SS=22	SS=10

Expert Solution

null hypothesis:Ho: all three treatments have equal means

alternate hypothesis:Ha: there are significant mean differences among the three treatments

applying two way ANOVA:

for (2,8) degree of freedom and 0.05 level critical value F=4.459

as test statsitic 28.0 is greater than crtiical value we reject null hypothesis

we have sufficient evidence at 0.05 level to conclude that there are significant mean differences among the three treatments

(Chapter 14) The following data were obtained from a repeated-measures study comparing three treatment conditions. a. Use a repeated measures ANOVA with α=.05 to determine whether there are significant mean differences among the three 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. b. Compute n2, the percentage of variance accounted...

1) The following data were collected from a repeated-measures study investigating the effects of 4 treatment conditions on test performance. Determine if there are any significant differences among the four treatments. State the null hypothesis. If you determine a significant treatment effect, use Tukey’s HSD test (overall α = .05) to determine which treatments differ from which other treatments. Also, compute the percentage of variance explained by the treatment effect (η2). Conclude with an appropriate summary describing what you found....
