The FREQ procedure provides easy access to statistics for testing for association in a crosstabulation table. In this example, high school students applied for courses in a summer enrichment program: ...

Data can be presented in many ways that make it quicker and easier to read. In this section we will look at some of these ways. It is important to choose the best way to present data. This is the data ...

Plotting the frequency of data falling within numeric ranges illustrates the diversity of your data. As an example, a teacher might wish to calculate and display her students' grades by tabulating the ...

Requests one-way to n-way frequency and crosstabulation tables and computes the statistics for these tables. Default: If you omit the TABLES statement, PROC FREQ generates one-way frequency tables for ...

In the case of frequency data, traditional discussions such as Rao (1973, pages 355-363, 391-412) consider asymptotic properties of maximum likelihood estimates and chi-square statistics under the ...
