Question

1. A researcher is interested in studying the effect that the amount of fat in the diet and amount of exercise has on the mental acuity of middle-aged women. The researcher used three different treatment levels for the diet and two levels for the exercise. The results of the acuity test for the subjects in the different treatment levels are shown below.

	Diet
Exercise	<30% fat	30% - 60% fat	>60% fat
<60 minutes	4	3	2
	4	1	2
	2	2	2
	4	2	2
	3	3	1
60 minutes	6	8	5
or more	5	8	7
	4	7	5
	4	8	5
	5	6	6

1. Perform a Two-way analysis of variance (ANOVA) and report the results using correct APA style; report whether significance was found for Factor A, Factor B, and/or an interaction between Factors A and B was found.
2. If the test statistic is significant, run a post hoc test to determine between what groups significance was found.
3. Report an effect size for all significant results.

Please show how to plug data into spss and get outcome and please show steps to use in spsss

Answer 1

Analysis of Variance

Source DF Adj SS Adj MS F-Value P-Value
row factor 1 90.133 90.1333 135.20 0.000
column factor 2 6.200 3.1000 4.65 0.020
row factor*column factor 2 18.467 9.2333 13.85 0.000
Error 24 16.000 0.6667
Total 29 130.800

where row factors are <60 minutes(1) and 60 minutes or more(2) and column factors are <30% fat(1),30% - 60% fat(2) and >60% fat.(3)

b) effect size:

effect size of row factor=90.133

effect size of cloumn factor=6.200

effect size of interaction=18.467
