Wait, is this a trick question? I could have sworn the answer was D) by location; id location. Oh well, time to go back to studying my SAS syntax.

I think the key here is understanding the difference between BY and CLASS statements in PROC MEANS. BY creates separate reports for each location, while CLASS groups the data by location within the same report.

I'm not sure, but I think 'group by location' might also work. Can someone explain why 'class location' is the best choice?

The correct answer is B) class location. This will group the data by the location variable and calculate the median for each location.

The median is the middle value when the data is arranged in numerical order. This PROC MEANS report shows the median for each location, which is exactly what the question is asking for.

I agree with Yuette, using 'class' is the correct way to group the data by location.
