The variation coefficient, also known as the coefficient of variation or CV, is a statistical measure used to compare the variability of different datasets. This index is calculated by dividing the standard deviation of a set of values by their mean, providing a relative measure of dispersion. In English, the variation coefficient can be referred to as "CV" or "coefficient of variation." It is commonly used in fields such as finance, economics, and engineering to compare the relative dispersion of various datasets. For example, "The coefficient of variation is a useful tool for comparing the volatility of different investment portfolios." This collection of English sentences and example sentences provides a comprehensive overview of the usage and applications of the variation coefficient.
