Standardized value is a statistical measure of how much a distribution varies or deviates from the average or mean. Another term for standardized value is normal deviate. The standardized value is derived from measuring the distance from the average and dividing by the standard deviation of the entire distribution. Standard deviation is how far a variable, such as the price of a stock, moves above or below the average value.
David B. Wilson, Ph.D., George Mason University. The standardized mean-difference effect size (d) is designed for contrasting two groups on a continuous dependent variable. It can be computed from means and standard deviations, a t-test, and a one-way ANOVA.Methods have also be developed for estimating d based on a dichotomous dependent variable.he standardized mean-difference effect size (d) is designed for contrasting two groups on a continuous dependent variable.
