2. Standard deviation
3. Range
4. Mean deviation
1. Mean
2. Standard deviation
3. Range
4. Mean deviation
Show Hint
Measures of dispersion help understand the variability in data and complement measures of central tendency like the mean.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Measures of variation or dispersion describe the spread or variability in a dataset.
The following are considered measures of dispersion:
- Standard deviation: Quantifies the amount of variation or dispersion in a dataset.
- Range: The difference between the maximum and minimum values in a dataset.
- Mean deviation: The average of the absolute deviations of data points from the mean.
Mean is a measure of central tendency, not dispersion. Therefore, the correct answer includes only options (B), (C), and (D).
