# Statistics expected value calculator

Expected Value (i.e., Mean) of a Discrete Random Variable . would calculate the standard deviation for this discrete distribution by first calculating the variance. This video provides an example of finding and interpreting the expected value and standard deviation using. This Expected Value calculator calculates the expected value, or the mean in advance, of a number set or group of numbers. What is Expected Value? Conceptually, the variance of a discrete random variable is the sum of the difference between each value and the mean times the probility of obtaining that value, as seen in the conceptual formulas below:.

Expected Value and Variance of Discrete Random Variables Knowing how to calculate expected value can be useful in numerical statistics, in gambling or other situations of probability, in stock market investing, or in many other situations that have a variety of outcomes. The mean and the expected value are so closely related they are basically the same thing. Rolling any other number results in no payout. You can think of an expected value as a mean , or average , for a probability distribution. To calculate the standard deviation we first must calculate the variance.
