The mean absolute deviation (MAD) is calculated by first finding the mean of the given data set, then calculating the absolute differences between each data point and the mean, and finally averaging those absolute differences. Without the specific data set provided in the question, it's not possible to directly calculate or confirm the correct answer. However, given the options, the most plausible value for a mean absolute deviation, which typically represents an average distance from the mean, is 10.28. This is because MAD values are generally closer to the scale of the data's spread and not as high as options A or D suggest. Option C could be plausible in some contexts, but B is a more typical range for many data sets, indicating a moderate spread around the mean.
