Question

Find and interpret the mean absolute deviation of the data. Round your answer to the nearest tenth, if necessary.

>Heights of 10-year old Octuplets<
61 | 61 | 61 | 61 | 61 | 61 | 61 | 61

Answer 1

• MAD = 0
• all octuplets are the same height; there is no deviation

Explanation:

You want the Mean Absolute Deviation of the data ...

61 | 61 | 61 | 61 | 61 | 61 | 61 | 61

Mean Absolute Deviation

The MAD is the mean of the absolute values of the deviations of the data from the mean. Here, the data are all the same, so the values are all equal to the mean. The deviations are all zero, and the mean of eight 0s is 0.

The mean absolute deviation is zero. All of the octuplets are the same height.
