Question

Question text True or False: Variance is the degree to which values of a random variable differ from the expected value.

Answer 1

The statement "Variance is the degree to which values of a random variable differ from the expected value" is TRUE

Step-by-step explanation:

A spread measure for a random variable distribution that determines the degree of difference between the values of a random variable and the expected value.

The random variable X variance is frequently written as Var(X) or $\sigma^2$    

For a discrete random variable, the variance is calculated by summing the square product of the difference between the random variable value and the expected value, and the associated probability of the random variable value, taken over all the random variable values.
