Anticipated value for a given investment. In statistics and probability analysis, expected value is calculated by multiplying each of the possible outcomes by the. One natural question to ask about a probability distribution is, "What is its center? " The expected value is one such measurement of the center. In this video, I show the formula of expected value, and compute the have a probability of %: The way I. De verwachtingswaarde berekenen Discuss Print Email Edit Send fan mail to authors. In regression analysis , one desires a formula in terms of observed data that will give a "good" estimate of the parameter giving the effect of some explanatory variable upon a dependent variable. Then the expectation of this random variable X is defined as. This article is about the term used in probability theory and statistics. Make a probability chart see: Now consider a weightless rod on which are placed weights, at locations x i along the rod and having masses p i whose sum is one. The expected value is also known as the expectation , mathematical expectation , EV , average , mean value , mean , or first moment. It may help to make a table of probabilities, as follows: You play a gambling game with a friend in which you roll a die. The test is graded according to the grading scheme below. This is in contrast to an unweighted average which would not take into account the probability of each outcome and weigh each possibility equally.

You should either list these or create a table to help define the results. If one rolls the die n times and computes the average arithmetic mean of the results, then as n grows, the average will almost surely converge to the expected value, a fact known as the strong law of large numbers.
