Many quality managers say that reducing variance is quality improvement. One tool the textbook suggests using is a Pareto Chart. According to our book, the best description of how a Pareto Chart works is:

Group of answer choices

It tallies all of the types and frequencies of problems with a product or a service.

A bar chart that plots frequencies of occurrences of problem types in decreasing order.

A bar plot that displays the frequency distribution of an observed performance characteristic.

A plot of measures of process performance monitored over time.
