Pareto Chart

The Pareto Chart is a very powerful tool for showing the relative importance of problems. It contains both bars and lines, where individual values are represented in descending order by bars, and the cumulative total of the sample is represented by the curved line. An 80% cut off line is also included to indicate where the 80/20 rule applies i.e. the vital few factors that warrant the most attention sit under the 80% cut off line.
