Test of frequency

[SASdevAnneMarie]

Hello Experts,

I have 200 rows for years 2021, 2022 and 2023 and a column with number of articles for each customers.

I would like to know if it's possible to compare the frequency of customers with proc freq. I would like to know if the customers buy the same number of article.

Thank you for your help !

What exactly do you mean by "compare"? What kind of "test of frequency"? Can you show an example of the type of question this "test" is supposed to answer? The Tables statement does measures of association and tests of agreement and distribution, which one(s) are appropriate depend on the specific type of question to be answered.

Now provide actual data as an example we can show some likely ways.

Or suggest alternates.
