Expected Value
Video lessons with examples and solutions to help High School students
learn how to calculate the expected value of a random variable; interpret it as
the mean of the probability distribution.
Expected Value: E(X)
Expected value of a random variable.
Statistics and Probability : Expected Value of a Random Variable
Computing the expected value of a random variable X.
Expected value discrete random variable
In this video you learn how to find the expected value of a discrete random variable. This one is the number of dots on a die.
Expected Value and Variance of Discrete Random Variables
An introduction to the concept of the expected value of a discrete random variable. I also look at the variance of a discrete random variable. The formulas are introduced, explained, and an example is worked through.
