Mean E(X) and Variance Var(X) for Continuous Random Variables : ExamSolutions - By ExamSolutions
If we took the same approach to finding the expected value for a continuous random variable as we took for a discrete random variable, we would have to sum up an infinite number of terms. Fortunately, we have the field of calculus to help us with what would otherwise be an insurmountable task. This video shows us how we can use integrals to find the expected value of a continuous random variable. This video also goes over finding the variance of a continuous random variable, which requires the use of the expected value itself. The basic skill set is the same, though, so it might be valuable to watch as well.
