The situation in the (much larger) population may be different. However, we're looking at just a tiny sample. We just saw that different diets and exercise levels show different mean weight losses. We'll explain it in a minute by visualizing our means in a chart.

This is what we call an interaction effect. In a similar vein, we see a somewhat stronger main effect for exercise with means running from 2.3 up to 8.6 kilos.ДЄn interesting question is whether the effect of exercise depends on the diet followed. This is the main effect for diet: the differences in weight loss attributable to diet while taking together all exercise levels. The Atkins and vegetarian diets resulted in 6.3 and 4.3 kilos of weight loss on average. Note that participants without any diet -all exercise levels taken together- lost an average of 2.8 kilos. It may take a minute to see the pattern in this table but I did my best to highlight it with colors. *Inspect means for diet, exercise and diet by exercise. Next, we'd like to inspect the frequency distribution for weight loss with a histogram.

We first want to confirm that we really do have 180 cases. We always want to have a basic idea what our data look like before jumping into any analyses. That is, we'll compare more than two means so we end up with some kind of ANOVA. We're going to test if the means for weight loss after two months are the same for diet, exercise level and each combination of a diet with an exercise level. These data -partly shown above- are in weightloss.sav. After two months, participants were asked how many kilos they had lost.
