A random variable whose probability distribution is a standard normal distribution.
— Suppose X#92;simN(#92;mu,#92;sigma). Then Z#61;#92;frac#123;x-#92;mu#125;#123;#92;sigma#125; is a standard normal random variable. In other words, any normal random variable can be standardized by subtracting the mean from the variable and dividing the difference by the standard deviation.
