Explain the marginal distribution. Explain how the marginal distribution of frequent binge drinking given in Example 4.33 is computed from the entries in the table given in Example 4.30.
Example 4.30
Add the margins to the table. We expand the table in Example 4.29 by adding the totals for each row, for each column, and the total number of all the observations. Here is the result:
In this study there are 7180 male students. The total number of binge drinkers is 3314, and the total number of individuals in the study is 17,096.
Example 4.33
The marginal distribution of binge drinking in percents. Here is the marginal distribution of the binge-drinking variable (in percents):
