Which of the following cannot be a method of measuring dispersion?
Show Hint
Measures of dispersion include Range, IQR, and Mean Deviation, but not Skewness
Updated On: Feb 11, 2026
- Range
- Interquartile range and quartile deviation
- Mean deviation or average deviation
- Skewness
Show Solution
The Correct Option is D
Solution and Explanation
Dispersion indicates how much data values vary from the central tendency.
Range is the difference between the maximum and minimum values.
The Interquartile Range (IQR) quantifies the spread between the first and third quartiles.
Mean deviation calculates the average absolute difference from the mean.
Skewness measures the asymmetry of a value distribution, not its spread. Thus, it is not considered a measure of dispersion.
