Dimensionless Measure of Dispersion
Which measure of dispersion is free from units (dimensionless)?
- Range
- Variance
- Standard deviation
- Coefficient of variance — Correct Answer
Explanation:
Correct Answer: Coefficient of variance (CV)
The Coefficient of Variance (CV) is a relative measure of dispersion and is free from units (dimensionless).
Formula
CV = (SD / AM) × 100
Where SD = Standard Deviation and AM = Arithmetic Mean.
Relative vs Absolute Measures
- Relative measures (no units): Coefficient of Variance (CV), Standard Error (SE)
- Absolute measures (have units): Range, Variance, Standard Deviation, Mean Deviation
Example: If AM = 20 and SD = 10, then CV = (10/20) × 100 = 50%.
