Standardizing Normal Variables

Suppose we have a normal population. We can represent it by a normal variable X. Further, we can convert any value of X into a corresponding value Z of the standard normal variable, by using the formula 90_standardizing normal variables.png

Where,

X = the value of any random variable

m = the mean of the distribution of the random variable

s = the standard deviation of the distribution

Z = the number of standard deviations from X to the mean of the distribution and is
known as the Z score or standard score.
