What is the mean deviation about the median for the values 2, 4, 6, 8 and 10?
Correct answer: B. 2.4
- A. 2.0
- B. 2.4
- C. 3.0
- D. 3.2
Explanation
The median is 6. The absolute deviations from 6 total 12, and dividing by the five observations gives a mean deviation of 2.4.

About Measures of Central Tendency and Dispersion
Central tendency includes mean, weighted mean, median and mode for raw and grouped data. Dispersion covers range, quartiles, interquartile range, variance, standard deviation and coefficient of variation, including the effect of changes in scale and the distinction between a representative centre and the spread around it.
