ITPEC IP October 2023 — Question 54 of 100
Chart (b) is a Pareto chart, which ranks defect causes by frequency and shows cumulative contribution. The descending bars reveal which causes account for the largest number of defects, while the cumulative line helps identify the vital few categories to prioritize for corrective action.
Answer (b)
Why not others:
- (a) is a cause-and-effect or fishbone diagram used to organize possible causes
- (c) is a scatter diagram used to examine correlation between two numerical variables
- (d) is a flowchart used to represent process sequence and decisions
Key rule: Use a Pareto chart to prioritize categories by count or impact; use a fishbone diagram to explore possible causes.
