# Expected value statistics formula

Expected value (EV) is a concept employed in statistics to help decide how Knowing how to calculate expected value can be useful in numerical statistics, in. You need to read the statistical calculation of the EV and make sense of it in real. This article is about the term used in probability theory and statistics. For other uses, see Expected value (disambiguation). In probability theory, the expected value of a random variable, intuitively, is the long-run .. This is because an expected value calculation must not depend on the order in which the possible outcomes. Expected Value (i.e., Mean) of a Discrete Random Variable. Law of Large Numbers: According to this formula, we take each observed X value and multiply it by its respective probability. We then add Sample Statistic, Population Parameter.
