I have 2 non-normal population datasets where the median is a better measure of central tendency.
To compare the spread of these 2 populations, can I calculate the coefficient of variation (CV) with population median and standard deviation σ? Or, is CV only applicable to sample mean and standard deviation?
- Median = 2,556; Mean = 2,797; σ = 1,910
- Median = 2,954; Mean = 3,436; σ = 1,959
