Has a Standard Normal Distribution?

The standard normal distribution is a normal distribution with a mean of zero and standard deviation of 1. The standard normal distribution is centered at zero and the degree to which a given measurement deviates from the mean is given by the standard deviation.

Which variable has a standard normal distribution?

A standard normal random variable is a normally distributed random variable with mean μ=0 and standard deviation σ=1. It will always be denoted by the letter Z.

How do you find the standard normal distribution?

The standard normal distribution (z distribution) is a normal distribution with a mean of 0 and a standard deviation of 1. Any point (x) from a normal distribution can be converted to the standard normal distribution (z) with the formula z = (x-mean) / standard deviation.
