Step-by-step explanation:

Mean Absolute deviation (MAD) of a data is the average absolute deviation from mean. To calculate Mean absolute deviation we take sum of all the values in the data as numerator and no of values in the data set as denominator. In the given case the two brands of tennis shoes have different mean absolute deviation.
