One-Way Frequency Report

This SAS^© script demonstrates the use of PROC FREQ to generate one-way frequency reports. It illustrates two distinct scenarios: first, generating a default frequency report for the 'type' variable from the SASHELP.CARS dataset, including frequency, percentage, cumulative frequency, and cumulative percentage. Second, it shows how to modify this report to display only frequency counts, by suppressing cumulative statistics (NOCUM) and percentages (NOPERCENT) via options on the TABLES statement. This allows for fine customization of frequency report output.

Data Analysis

Type : SASHELP

The script uses the 'cars' dataset from the SASHELP library, which is a standard example dataset provided with SAS installations, requiring no external data management or internal creation.

1 Code Block

PROC FREQ

Explanation :
This block executes PROC FREQ with default parameters for the 'type' variable from the SASHELP.CARS dataset. The resulting report includes frequency, percentage, cumulative frequency, and cumulative percentage, which is the standard behavior of PROC FREQ without specific options on the TABLES statement. A descriptive title is added to the report.

2 Code Block

PROC FREQ

Explanation :
This block also executes PROC FREQ on the 'type' variable, but uses the 'nocum' and 'nopercent' options on the TABLES statement. These options suppress the display of cumulative statistics and percentages in the frequency report, respectively, showing only raw frequency counts. A specific title is used for this report.
