GRIM (Granularity-Related Inconsistency of Means)#
The GRIM test checks whether a reported mean is mathematically consistent with the reported sample size, assuming integer-valued data. For example, if a study reports a mean of 1.47 for 20 participants on a Likert scale, GRIM checks whether any combination of 20 integers can produce exactly that mean.
