I was just wondering if there was a procedure to check whether missing data are MCAR or MAR?

My thought is checking their frequency, and make a hypothesis test H0: mean of freq =xx .

Thanks to all. My sample does not meet the normality assumptions, so I used the Whitney-Mann to test between the complete and missing scores. I appreciate the replies.
