Question
Which measure of dispersion is least affected by sample size?RangeVarianceCoefficient of VariationMean Deviation
Solution
The measure of dispersion that is least affected by sample size is the Coefficient of Variation. This is because the Coefficient of Variation is a standardized measure of dispersion, meaning it is independent of the unit of measurement and the size of the sample. It is calculated as the ratio of the standard deviation to the mean, and is often expressed as a percentage. This makes it a useful tool for comparing the variability of data sets with different units or scales.
