Z Score - Normal and Standard Normal Distribution - Formula and Examples - How to Interpret Results
Показать описание
An observation's Z Score tells us how many standard deviations the observation x is from the mean µ.
We learn the formula for calculating the z score and learn how to use it with an example. The process is known as standardising the random variable.
