ITPEC IP April 2025 Question 71
ITPEC IP April 2025 — Question 71 of 100
Pareto chart — it combines descending category bars with a cumulative-percentage line to reveal improvement priorities.
Complaint types are ordered from most frequent to least frequent. The bars show the count for each type, while the line shows how much of the total is covered cumulatively. This helps focus action on the small number of categories producing most complaints.
Answer (d)
Why not others:
- (a) PERT chart models project activities and dependencies
- (b) Control chart plots process values over time against control limits
- (c) Cause-and-effect diagram organizes possible causes of a problem
Key rule: A Pareto chart prioritizes categories by observed frequency or impact; a fishbone diagram then helps explore why the priority problem occurs.
