General form, basic FREQ procedure: PROC FREQ <DATA=SAS-data-set>; RUN; where SAS-data-set names the data set to be used.

By default, PROC FREQ creates a one-way table with the frequency, percent, cumulative frequency, and cumulative percent of every value of all variables in a data set.

Variable	Frequency	Percent	Cumulative Frequency	Cumulative Percent
Value	Number of observations with the value.	Frequency of the value divided by the total number of observations.	Sum of the frequency counts of the value and all other values listed above it in the table.	Cumulative frequency of the value divided by the total number of observations.

For example, the following FREQ procedure creates a frequency table of all variable values in the data set Parts.Widgets. proc freq data=parts.widgets; run;

ItemName	Frequency	Percent	Cumulative Frequency	Cumulative Percent
Bolt	2930	34.52	2930	34.52
