ITPEC IP October 2020 — Question 53 of 100
A Pareto chart orders categories from highest to lowest frequency and adds a cumulative curve. Grouping detected bugs by cause shows which few causes account for most defects, helping the team prioritize quality improvement.
Answer (c)
Why not others:
- a scatter diagram examines the relationship between two quantitative variables
- a cause-and-effect diagram organizes possible causes of a problem
- a histogram displays the frequency distribution of values across intervals
Key rule: Descending category bars plus a cumulative-percentage line identify a Pareto chart and support focus on the vital few causes.
