Question
Roberta is the project manager of the KJL Project for her company. She is creating a chart that will help categorize the problems discovered during the quality control inspection process. She wants to create a chart where she can categorize the number of instances of problems and rank the problems based on frequency. Which chart should Roberta create?

Why each option
Roberta needs a Pareto Chart, which displays defect categories as ranked bars from most to least frequent, enabling identification of the vital few causes responsible for most quality problems.
A Pareto Chart combines a bar chart and cumulative line graph to categorize defects by frequency and rank them from highest to lowest occurrence, directly supporting the 80/20 principle that most problems stem from a few key causes. It is the standard quality management tool specifically designed for categorizing problem instances and ranking them by frequency. This makes it the exact tool suited for Roberta's quality control inspection analysis.
A scatter diagram shows the correlation or relationship between two variables, not a ranked frequency count of categorized problem types.
A fishbone (Ishikawa) diagram is a cause-and-effect tool used to identify root causes of a single problem, not to categorize and rank multiple problem types by frequency.
A control chart tracks process performance over time against upper and lower control limits to detect variation, not to rank defect categories by number of occurrences.
