Which PROC FREQ option suppresses cumulative frequencies?

The option that suppresses cumulative frequencies in PROC FREQ is indeed the one that specifies 'NOCUM'. When this option is included in the PROC FREQ statement, it instructs SAS to generate the frequency table without displaying the cumulative frequency counts for each category. This is particularly useful when the user wants a straightforward representation of the count of occurrences for each category without the additional layer of cumulative totals, making the output cleaner and easier to read in some scenarios.

In PROC FREQ, the presence of cumulative frequencies can sometimes clutter the output or detract from the specific analysis being carried out. By using the 'NOCUM' option, a user can focus solely on the individual counts, which are often the primary interest when analyzing frequency distributions.

The other options have different functionalities. For instance, 'NOROW' suppresses row percentages, 'NOPERCENT' removes all percentage calculations from the output, and 'NOCOL' suppresses column percentages. Each of these options is effective for modifying different aspects of the PROC FREQ output but does not specifically target cumulative frequencies like 'NOCUM' does.
