Pareto chart

Pareto charts help improve processes by identifying the root causes of an event. They rank categories from most frequently occurring to least frequently occurring. These charts are often used for quality control, allowing the root cause of problems to be identified and, if possible, corrected. Pareto charts contain a cumulative line that represents the percentage of the total of all vertical or horizontal bars.
