Example Using Graph Builder<br />

Figure 10.5 Example of Calories Versus Total fat g by Carbohydrate g<br />

Carbohydrate g is a continuous variable with many values, so Graph Builder uses the percentiles to create<br />

five ranges of carbohydrate g levels. About the same number of points are displayed in each group. You can<br />

see that the relationship between calories <strong>and</strong> fat is relatively strong for each level of carbohydrate. It appears<br />

that carbohydrates adds additional predictive ability.<br />

Now that you have determined that carbohydrates have a significant impact on calories, combine the five<br />

scatterplots into one scatterplot to directly compare the lines. You still want to identify the carbohydrate<br />

levels.
