Variation, on the other hand, focuses on the range of differences observed within a group, population, or set of data, reflecting diversity, such as in the coloration of butterfly wings within a species. 9 While deviation is typically measured against a specific benchmark or expectation, ...

This metric is calculated as the square root of the variance. This means you have to figure out the variation between each data point relative to the mean. Therefore, the calculation of variance uses squares because it weighs outliers more heavily than data that appears closer to the mean. T...
答案解析: Coefficient of variation, CV = standard deviation / mean. The standard deviation is the square root of the variance, or 4½ = 2. So, CV = 2 / 10 = 20%. 统计:共计66人答过,平均正确率62.12% 问题:进入高顿部落发帖帮助...
What Is Variance Used for? Variance measures the degree of spread in a data set from its mean value. It shows the amount of variation that exists among the data points. Visually, the larger the variance, the "fatter" aprobability distributionwill be. In finance, if something like an invest...
Genetic variation is the variation in alleles and genes, both within and among populations. Think of a population as a family unit. Within your family of closely-related individuals there is genetic variation. Within a neighborhood, there are many families, and so there is also genetic variation...
