Discover the Formula Behind the Normal Line in Statistics - postfix

What is a normal distribution?

So, what is the normal line? Simply put, it's a straight line that is used to approximate the behavior of a normal distribution. A normal distribution is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. The normal line formula is used to calculate the z-score, which indicates how many standard deviations an observation is from the mean. This allows analysts to identify outliers and make predictions about future data points.

To calculate the z-score, you'll need to use the following formula:

How it works

You can use statistical tests, such as the Shapiro-Wilk test, to determine if your data is normally distributed.
