Coefficient of variation - Wikipedia
https://en.wikipedia.org/wiki/Coefficient_of_variationThe coefficient of variation (CV) is defined as the ratio of the standard deviation to the mean , It shows the extent of variability in relation to the mean of the population. The coefficient of variation should be computed only for data measured on a ratio scale, that is, scales that have a meaningful zero and hence allow relative comparison of two measurements (i.e., division of one measurement by the other). The coefficient of variation may not have any meaning for data on an interval scale. …
Variationskoefficient – Wikipedia
https://sv.wikipedia.org/wiki/VariationskoefficientVariationskoefficient är ett spridningsmått som används inom sannolikhetslära och statistikberäkningar.Vid observationer på olika skalor ex. 1,2,3,4,5 och 100,200,300,400,500 kommer standardavvikelserna vara olika (större vid högre skalor) även om de procentuellt sett är lika. Variationskoefficienten är en normaliserad standardavvikelse och uttrycker …
Coefficient of variation - Wikipedia
en.wikipedia.org › wiki › Coefficient_of_variationStatistical parameter In probability theory and statistics, the coefficient of variation, also known as relative standard deviation, is a standardized measure of dispersion of a probability distribution or frequency distribution. It is often expressed as a percentage, and is defined as the ratio of the standard deviation σ {\displaystyle \ \sigma } to the mean μ {\displaystyle \ \mu }. The CV or RSD is widely used in analytical chemistry to express the precision and repeatability of an ...
