Can someone walk me through the steps to find “the effect size for each of my factors and the interaction, and to explain the results” within SPSS…it has to be SPSS.

Here is the work I did in SPSS so far: It is for a two-way ANOVA

Tests of Between-Subjects Effects

Dependent Variable: Acuity Results

Below was the question I had to answer, regarding my SPSS work above.

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.
