PARETO ANALYSIS

The "Pareto principle" is the idea that by doing 20% of the work you can generate 80% of what you would get from doing the entire job.

Here are the steps:

2) Arrange the rows in the decreasing order of frequency of the causes.
3) Find the cumulative percentages.
4) Plot with causes on x- and cumulative percentage on y-axis.
5) Join the above points to form a curve.
