• most of the data values are different from the mean.
• most of the data values are similar (close) to the mean.
• most of the data values are greater than the mean.
• most of the data values are far from the mean.

Explanation:

MAD (Mean Absolute Deviation) measures the average distance of data points from the mean. A small MAD means most data values are close to the mean, with little variation from it.

Answer:

B. Most of the data values are similar (close) to the mean.
