What is the correct syntax for PROC MEANS?

• A. PROC MEANS STATISTICS=statistics; VAR variable(s); RUN;
• B. PROC MEANS DATA=dataset; VAR variable(s); RUN;
• C. PROC MEANS DATA=statistics; VAR variable(s); RUN;
• D. PROC MEANS DATA=dataset; STATISTIC=statistics; RUN;

Answer: (B)

The correct syntax for PROC MEANS includes specifying a dataset using the DATA= option, which allows the procedure to know which data to analyze. The VAR statement is used to list the variables for which you want to compute descriptive statistics. In this case, B accurately reflects the proper structure of the PROC MEANS statement by including the DATA= option followed by the name of the dataset, and the VAR statement to define the specific variables of interest. This allows users to request summary statistics such as mean, standard deviation, minimum, and maximum for selected numeric variables in the specified dataset. Choosing the correct dataset is crucial because PROC MEANS processes only the data contained in that dataset. Without it, as seen in the other options, the syntax either lacks the necessary component or misrepresents the function of the procedure, leading to potential errors or unintended results when executing the code.
