Pareto Chart

A vertical bar graph showing the bars in descending order of significance, ordered from left to right. It helps to focus on the vital few issues, rather than the trivial many. An extension of the Pareto principle suggests that the significant items in any given group normally constitute a relatively small portion of the items in the total group. Conversely, a majority of the items will be relatively minor in significance — the 80 / 20 rule.
