This template allows you to enter up to 100 individual data points, and the histogram will be displayed automatically to reflect your data. The more data there is, the more accurate the histogram will be.

It describes a statistical phenomenon that a small number of high values contribute more to the total than a high number of low values. The focus of the Pareto Analysis is to identify the “vital few” from the “trivial many” and make it possible to attack the 80 percent of the problems to obtain the maximum benefits.
