WebJun 19, 2024 · To get to the point, for N consecutive intervals of size h with extremely low p, the mean and the variance are equal. Now, in practice, this is usually not the case in observational studies. The reason is that we cannot take into account all the factors for heterogeneity in the study. WebDefinition. The 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.
