To calculate the mean absolute deviation (MAD) of the numbers 65, 90, 85, 70, 70, 95, and 55, first find the mean, which is 75. Then, calculate the absolute deviations from the mean: |65-75|, |90-75|, |85-75|, |70-75|, |70-75|, |95-75|, and |55-75|, resulting in the values 10, 15, 10, 5, 5, 20, and 20. The average of these absolute deviations is the MAD, which equals approximately 11.43.
