Question

Define, describe, and compare the following questions:

What are a normal distribution and a standard normal distribution?

What are their properties?

Answer 1

The Standard normal distribution has the mean of 0 and standard deviation of 1.An point x can be converted into standardized score by using the formula z score = ( X-Mean)/Standard deviation. A zscore tell us how many standard deviations are above or lower the mean.

A normal distribution can have mean and standard deviation.A normal distribution can be converted into standard normal distribution using the z formula. Both distributions followed empirical rule.
