Key Differences Between PROC MEANS and PROC SUMMARY in SAS

The main difference between PROC MEANS and PROC SUMMARY in SAS lies in their functionality and outputs. PROC MEANS is primarily used for generating descriptive statistics, such as mean, median, standard deviation, and range, for specified variables in a dataset. On the other hand, PROC SUMMARY is a more versatile procedure that allows for customization of output statistics and calculations, making it suitable for more complex summary tasks.

Additionally, PROC MEANS produces output in a tabular format by default, while PROC SUMMARY offers the flexibility to customize the output format and variables included in the summary.

Overall, while PROC MEANS is a quick and easy way to generate standard descriptive statistics in SAS, PROC SUMMARY provides more customization options for summarizing data in a way that meets specific requirements.
