This example teaches you how to create a Pareto chart in Excel. The Pareto principle states that, for many events, roughly 80% of the effects come from 20% of the causes.
On the ribbon, click the Insert tab, and then click (the Statistical chart icon), and in Histogram section, click Pareto. Tip: Use the Chart Design and Format tabs to customize the look of your chart. If you don't see these tabs, click anywhere in the Pareto chart to display them on the ribbon.
