Expected value refers to the anticipated value of anassetin the future. The EV of a random variable gives a measure of the center of the distribution of the variable. The EV is essentially the long-term average value of the variable. Because of thelaw of large numbers, the average value ...
Expected value, in general, the value that is most likely the result of the next repeated trial of a statistical experiment. The probability of all possible outcomes is factored into the calculations for expected value in order to determine the expected

expected value n (Statistics)statisticsthe sum or integral of all possible values of a random variable, or any given function of it, multiplied by the respective probabilities of the values of the variable. Symbol:E(X).E(X) is the mean of the distribution;E(X–c) =E(X)–cwherecis a...

The expected value is a type of calculation in mathematical statistics that measures of the center of a probability distribution.
DEFINING EXPECTED VALUE The expected value concept uses two main mathematical concepts—random variables and probabilities. To understand a random variable, let us assume that an experiment results in a certain number of outcomes and each of the outcomes is assigned a numerical value. A random ...
To find the expected value, use the formula: E(x) = x1 * P(x1) + ... + xn * P(xn). In other words, you need to: Multiply each random value by its probability of occurring. Sum all the products from Step 1. The result is the expected value. Can the expected value be negati...
This problem is a crucial part of modern ecological analyses; each point in P represents a species in d-dimensional trait space, and the goal is to compute the statistics of a geometric measure on this trait space, when subsets of species are selected under random processes. We present ...
