Ever wonder how doctors know that you are in the 45th percentile in height? Or why right after the warrenty wears off on your tablet and then the tablet breaks? Or how the SAT knows what scores to give their test takers if each test is different? All of these questions can be answered if you know the basics of normal distributions and how they work.

Goal:

The goal of this site is to give you a foundation for normal curves. After going through the content, you should be able to identify a normal distribution from a non-normal distribution, understand the area under the curve as representing the percent of data below a data point, and you will be able to calculate a z-score and find the percent under the curve using a table. At the end you can practice calculating a z-score by finding your height percentile.
