The Mean Group Diff statistic is a measure of the difference between the means of two groups. It is calculated by subtracting the mean of the first group from the mean of the second group. The result is a positive number if the mean of the second group is greater than the mean of the first group, and a negative number if the mean of the first group is greater than the mean of the second group.
