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.
