Expectations and Moments of Random Variables

  • Ron C. Mittelhammer
Chapter

Abstract

The definition of the expectation of a random variable can be motivated both by the concept of a weighted average and through the use of the physics concept of center of gravity, or the balancing point of a distribution of weights. We first examine the case of a discrete random variable and look at a problem involving the balancing-point concept.
