WebThe expected value of a discrete random variable X is the mean value (or average value) we could expect X to take if we were to repeat the experiment a large number of times. It is calculated with: E(X) = ∑x. P(X = x) The expected value is also known as the mean μ of the random variable, in which case we write: μ = ∑x. WebIn this example the middle numbers are 21 and 23. To find the value halfway between them, add them together and divide by 2: 21 + 23 = 44. then 44 ÷ 2 = 22. So the Median in this example is 22.
