MCAR = Missing Completely at Random. MAR = Missing at Random. MNAR = Missing Not at Random. For the MCAR data, there is no relationship between IQ and the job performance ratings. A case with a lower IQ is just as likely to be missing as a case with a higher IQ. With MAR data, all cases with missing job performance ratings are participants with a lower IQ. With the MNAR data, IQ can't be used to account for the pattern of missingness because IQ doesn't explain why the cases are missing. The examples are based on Enders (2010).
