The mean or expected value of X is defined by E(X) = sum xk p(xk). Interpretations: (i) The expected value measures the center of the probability distribution. Anticipated value for a given investment. In statistics and probability analysis, expected value is calculated by multiplying each of the possible outcomes by the. There are some things you can cancel in yours. (E((E(X)))2=(E(X))2, since the expected value of an expected value is just that. It stops being random.

|Expected value of expected value||Your email address will not be published. It is first assumed that X has a density f X x. You can think of an expected value as a meanor averagefor a probability distribution. In probability theorythe expected value of a random variableintuitively, good gaming nicknames the long-run average value of repetitions of the experiment it represents. However, if the terms are absolutely summable, then the order in which you sum becomes irrelevant.|

The expected value of a random variable X is based, of course, on the probability measure Expected value of expected value for the experiment.
