Frequency tables show the distribution of variable values, both as percentages of a total and as counts of data. SAS software's FREQ procedure creates one-way frequency tables and two-way and n-way crosstabulation tables. It can also compute measures of association and of agreement, and organize output by stratification variables. The following lesson will show you how to use PROC FREQ to perform basic data analysis.

Product	Frequency	Percent	Cumulative Frequency	Cumulative Percent
Apples	92	58.60	92	58.60
Oranges	65	41.40	157	100.00

This lesson contains 23 pages and takes approximately 30-45 minutes to complete.
