Probability Chart in Excel

You will learn how to do mathematical calculation, and insert a probability chart (to be exact it is normal distribution probability plot).But first, you need a data that looks like this:


dataClick on home tab.

ribbon home

Click on a value in the data, and Sort & filter to choose Sort from smallest to largest.
