Wird der Erwartungswert als erstes Moment aufgefasst, so ist er eng verwandt mit den Momenten höherer Ordnung. 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 expected value EV of a set of outcomes is the sum of the individual products of the value times its probability. But finally I have found that my answers in many cases do not differ from theirs. 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. Jensen's inequality states that. By "continuity from below" see, e. Assign values to each possible outcome. This is sometimes called the law of the unconscious statistician.
