Pie Chart Versus Pareto Chart Examples 7 and 8 show a Pareto chart and pie chart for job procurement data. For such data, why is it generally better to use a Pareto chart instead of a pie chart?
Example 7:
Pareto Chart: How to Find a Job The following Minitab generated Pareto chart shows how workers found their jobs (based on data from The Bernard Haldane Associates). We see that networking was the most successful way workers found their jobs. This Pareto chart suggests that instead of relying solely on such resources as school job placement personnel or newspaper ads, job applicants should actively pursue networking as a means for getting a job.

Example 8
Pie Chart: How to Find a Job The Minitab-generated pie chart on the preceding page is based on the same data used for the Pareto chart in Example 7. Construction of a pie chart involves slicing up the circle into the proper proportions that represent relative frequencies. For example, the category of networking represents 61% of the total, so the slice representing networking
should be 61% of the total (with a central angle of 0.61 * 360° = 220°).
