WebSep 7, 2024 · Variance reflects the degree of spread in the data set. The more spread the data, the larger the variance is in relation to the mean. Variance example To get variance, … WebNov 7, 2024 · The variance of a data set tells you how spread out the data points are. The closer the variance is to zero, the more closely the data points are clustered together. When working with sample data sets, use the following formula to calculate variance: [3] = ∑ [ ( - x̅) ] / (n - 1) is the variance. Variance is always measured in squared units.
Web1 day ago · To replicate these observations, we performed a similar analysis using only DNA-based measurements from published datasets (10, 16, 40) (fig. S30). Both the fraction of coding mutations and the odds of detecting a deleterious mutation decreased over the germ cell life cycle in the independent datasets (fig. S30).
