Measures of Dispersion
Which of the following is the Dispersion of a population measured by?
- Mean, median and mode
- Standard deviation, mean deviation and range — Correct Answer
- Sampling bias and non-response error
- Primary and secondary data
Explanation:
Correct Answer Explanation
Dispersion of a population is measured by Standard Deviation, Mean Deviation, and Range.
Two Population Characteristics:
- Central Tendency: Mean, Median, Mode — measures the 'average' level.
- Dispersion: Standard Deviation, Mean Deviation, Range — measures the 'spread' or variability.
Exam Tip:
- Range = Maximum value − Minimum value (simplest measure of dispersion).
- Standard Deviation is the most commonly used measure of dispersion in statistics.
- A population with high dispersion has values that are widely spread from the mean.
