Random Data Selection

light — Sat, 21 May 2016 03:51:54 GMT

Hello Community Members,

This question has to do not only with SAS but also with hypothesis testing. If I have a randomly generated frequency table, how can I test that the numbers ( that correspond to frequencies) in that table are in fact random? How can I use SAS to help?

Any advice is appreciated.

Thank you.

Since it is about Hypothesis, you should post it at Statistical Forum (another position at this site). Maybe you could use PROC FREQ + Chisq Test to test whether there are association between row variable and column variable. proc freq ; table a*b/chisq; run;

I agree with @Ksharp

I've moved your question to the stats forum.

Also, chi square is the correct test to check the distribution of a frequency.

But it partly depends on your data. Using a histogram may also be appropriate. If your simulating data look into Rick Wicklins book on simulating data in SAS.
