The mean absolute deviation (MAD) tells you "how far data values are, on average, from the mean." It is a measure of the dispersion or spread of a data set, indicating how much the values typically deviate from the mean value. The other options you provided refer to different statistical concepts:
- The difference between the highest and lowest values refers to the range of the data set.
- The middle number in a data set refers to the median.
- The most frequent value in a data set refers to the mode.
So, the correct answer is: **How far data values are, on average, from the mean.**
- The difference between the highest and lowest values refers to the range of the data set.
- The middle number in a data set refers to the median.
- The most frequent value in a data set refers to the mode.
So, the correct answer is: **How far data values are, on average, from the mean.**
