The mean absolute deviation is the average of the positive distances of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out). The MAD helps determine whether the set's mean is a useful indicator of the values within the set.
The mean absolute deviation of a set of data is the average distance between each data value and the mean.The mean number of contacts stored and the distance each data value is from the mean is shown below.his means that the average distance each data value is from the mean is 12.5 miles per hour.a. BIRDS The table shows the maximum flying speeds of the ten fastest birds worldwide. Find the mean absolute deviation of the set of data.
