The coefficient of variation is 0.42 (8% ÷ 19%). The third investment, bond, ABC, has a volatility of 5% and an expected return of 8%. The coefficient of variation therefore is 0.63 (5% ÷ 8%). Investors' risk aversion differs from one investor to another. How...
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 investment has a greater variance,...

PH is a quantitative trait with pleiotropic effects, and is affected by genetic variation and environmental impacts (Ma J et al. 2019). Mutant analysis, interaction analysis of plant hormones, and quantitative genetic analysis tools have been applied to dissect the genetic architecture of PH (Wang...

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...
