The Mean Absolute Deviation (MAD) is calculated by taking the average of the absolute deviations from the mean. The mean of months 2 through 5 is 176.25. The absolute deviations are 31.25, 16.25, 3.75, and 43.75. The average of these deviations is 23.75, which falls in the range greater than 20 but less than or equal to 25.
