Pareto Chart

The Pareto chart is one of the seven basic tools of quality control. It can be leveraged to assess the most frequently occurring defects in a series. The premise behind the chart is the Pareto principle which states that roughly 80% of the effects come from 20% of the causes. Individual values are represented in descending order by bars, and the cumulative total is represented by the line.
