Question

Which statement from PROC MEANS contains valid syntax for creating a summary output table?

a. out=work.summary mean;
b. out work.summary mean(Weight)=TotW;
c. output out work.summary Weight=TotW;
d. output out=work.summary mean(Weight)=TotW;

Answer 1

The correct syntax for creating a summary output table in PROC MEANS is "output out=work.summary mean(Weight)=TotW;" which calculates and outputs the mean of the variable 'Weight', naming the new column 'TotW' in the output table.

Step-by-step explanation:

The student is asking about the correct syntax for creating a summary output table using the PROC MEANS procedure in SAS. The correct statement is option d: output out=work.summary mean(Weight)=TotW; This statement is directing PROC MEANS to output the means for the variable 'Weight' into a new table named 'summary' in the 'work' library and to rename the variable as 'TotW' in the output table.

To break it down step-by-step:

• output specifies the output statement to create a result dataset.
• out=work.summary creates a new table called 'summary' in the 'work' library.
• mean(Weight)=TotW calculates the mean of the 'Weight' variable and names the new variable 'TotW' in the output table.

This syntax enables customization of the output dataset and the summary statistics that SAS generates.
