A Pareto chart is used to demonstrate which of the following?

A Pareto chart is particularly effective for illustrating the causes of a problem and their frequency, following the principle that a small number of causes often contribute to the majority of a problem's effects. This chart displays categories of data in descending order of frequency or impact, allowing viewers to identify the most significant issues that should be prioritized for solutions. The visual format highlights the "vital few" versus the "trivial many," making it easier for teams to focus on the factors that will result in the greatest improvement when addressed. By concentrating on the most prevalent causes, organizations can allocate resources more efficiently and implement changes that will have the most substantial impact on quality and performance.

In this context, options that might explore correlations, process steps, or control limits would not capture the essence of what a Pareto chart is designed to achieve, demonstrating its specific utility in quality improvement and problem-solving initiatives.
