This chapter 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. In this example, we will see that roughly 80% of the complaints come from 20% of the complaint types.
To create a Pareto chart in Excel 2016, execute the following steps.
1. Select the range A3:B13.
