The expected value formula changes a little if you have a series of trials (for example, a series of coin tosses). When you have a series of trials. The expected value plays important roles in a variety of contexts. In regression analysis, one desires a formula in terms of observed data that will give a "good" Definition · General definition · Properties · Uses and applications. The formula for the expected value is relatively easy to compute and involves several multiplications and additions.
The intuition however remains the same: A discrete random variable is a random variable that can only take on a certain number of values. Independent variables are a notable case of uncorrelated variables. The convergence is relatively slow: Note on the formula: Back to Top What is Expected Value in Statistics used for in Real Life?
