Proc Freq

This procedure is primarily used to produce frequency counts. However, what distinguishes this procedure between others is its ability to compute Chi-Square tests, measures of association, and agreement for contingency tables. The syntax of the procedure is as follows:

Proc Freq <options>;
  Tables requests < options >;
  By variables;
  Exact statistic-options </ computation-options>;
  Output <OUT = SAS-dataset> options;
  Tables requests </options>;
Test options;
  Weight variable < / option >;

We will use the simplest form of version of Proc Freq and explore the results in a dataset containing information on the Class, Height, and Weight of children in a school:

Data Class;
Input ID Class $ Height $ Weight $;
Datalines;
1 A Over5.7 Above50 1 0 1
2 A Over5.7 Above50 1 1 0
3 B Over5.7 Below50 1 1 .
4 B Under5.7 Below50 1 1 1
5 A Over5.7 Below50...
