Which option below is TRUE regarding the PROC FREQ procedure?

• A. It exclusively analyzes numeric data values
• B. It calculates relative and cumulative percentages
• C. It cannot handle missing values
• D. It generates graphs automatically

Answer: (B)

The PROC FREQ procedure in SAS is designed to analyze categorical data and is highly effective for producing frequency tables. One of its capabilities is to calculate relative and cumulative percentages, which provide insights into how often different values or categories occur relative to the total and in a cumulative manner as you progress through ranked categories. This is particularly useful for understanding distributions within the data. When using PROC FREQ, the procedure also presents options to handle various data types and conditions, including the treatment of missing values and the ability to generate graphical representations of frequencies if specified, contrary to what the other choices suggest. Therefore, the ability to calculate relative and cumulative percentages makes this statement true and highlights a key functionality of the PROC FREQ procedure.
