### Calculating expected value

By calculating expected values, investors can choose the scenario that is most likely to The expected value (EV) is an anticipated value for a given investment. Definition of expected value & calculating by hand and in Excel. Includes video. Find an expected value for a discrete random variable. Definition of expected value & calculating by hand and in Excel. Includes video. Find an expected value for a discrete random variable.
The formal definition subsumes both of these and also works for distributions which are neither discrete nor continuous; the expected value of a random variable is the integral of the random variable with respect to its probability measure. For example, suppose we toss a coin where the probability of heads is p. However, in more rigorous or advanced statistics classes like these , you might come across the expected value formulas for continuous random variables or for the expected value of an arbitrary function. 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. Back to Top Find an Expected Value for a Discrete Random Variable You can think of an expected value as a mean , or average , for a probability distribution.
