Hello,
I need to find the time period (3 month increments; Jan-Mar, Feb-Apr, etc.) where the majority of my data points (rates) are. The dataset extends 2 years. Would it be best to create a graph/visualization such as a scatterplot? Or use a proc freq statement on the dates? Any help would be greatly appreciated.
If you have a date associated with the measures then 1) make sure it is a SAS date value (NOT character or numeric like 20180120 that only looks date-like) and 2) use a format like YYQ6. for the variable.
Then procs like Freq will group the variables into calendar quarters and display the value like 2017Q1 (first quarter of 2017)
"majority of data points" might mean something different to me than it means to you
Nevertheless, I can think of two approaches
Thank you!

Thank you. The proc freq did the trick. I did a cross-tabulation, so I could see the frequency of the ID's by date and quarter.
