Answer:
Most of the data values are similar (close) to the mean
Step-by-step explanation:
The Mean Absolute Deviation (MAD) use the absolute difference between the mean and each term, so it cannot tell if the values are greater or less than the mean.
If the values of the set of data are close to each other, then they will be close to the mean, therefore the absolute deviation will be small for each value, and in consequence, the MAD will be small. This is what happens in the example given.
Similarly, if the values of the set of data are very different from each other, the MAD will be high.
