Which tool is a vertical bar graph with values plotted in decreasing order of frequency and commonly used in quality control?

• A. Organizational development
• B. Pareto chart
• C. Overhead
• D. Ownership interest

Answer: (B)

A Pareto chart is a vertical bar graph that shows categories in order from most frequent to least frequent, with the height of each bar representing how often that category occurs. A cumulative line is often added to indicate the running total of frequency or impact as you move from left to right. In quality control, this format helps teams quickly identify the most significant problems to address—the few categories that cause the majority of defects or failures—so improvement efforts can be focused where they’ll have the greatest effect, aligning with the idea that a small number of causes often account for most problems. Other options aren’t about this prioritization tool: organizational development refers to improving organizational effectiveness and people practices, overhead denotes indirect costs, and ownership interest relates to equity or stake in a company.
