Introduction

You can use PROC FREQ to create one-way, two-way (row and column), and three-way (page, row, and column) tables. You can output counts and percentages as well as statistics such as chi-square and Fisher’s Exact test. This chapter will show you examples of these tasks.

Creating a Data Set to Demonstrate Features of PROC FREQ

The first step is to have some test data to demonstrate features of PROC FREQ. To this end, you can run the program ...
