Hi,

Interesting questions. Let's take a closer look. I also attacked one supporting article.

RESPONSE:

1. What is a brief introduction (less than 100 words) of Pareto Charts?

A Pareto chart is simply a histogram where the categories are sorted from highest to lowest percentage of some sum total. The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right. In this way the chart visually depicts which situations are more significant. (http://www.asq.org/learn-about-quality/cause-analysis-tools/overview/pareto.html). A pareto chart is used to graphically summarize and display the relative importance of the differences between groups of data. It can be constructed by segmenting the range of the data into groups (also called segments, bins or categories) (http://www.isixsigma.com/library/content/c010527a.asp).

Thus is is a bar chart used to separate the "vital few" from the "trivial many." These charts are based on the Pareto Principle, which states that 20 percent of the problems have 80 percent of the impact. The 20 percent of the problems are the "vital few" and the remaining problems are the "trivial many." A bar chart used to separate the "vital few" ...
