EXAM Question 1: Which pairing correctly classi�es two common quality data types?
Choices:
1) Defective-unit count—discrete attributes; shaft diameter—continuous variables 2) Both are ordinal data 3) Both are nominal data 4) Defective-unit count—continuous variables; shaft diameter—attributes Correct Answer: Defective-unit count—discrete attributes; shaft diameter—continuous variables Explanation: Counts of defectives are discrete attribute data, while measured dimensions such as shaft diameter are continuous variables data.Page 1
Question 2: A team wants to show the sequence of steps, decisions, and rework
loops in an order-entry process. Which tool should it use?
Choices:
1) Scatter diagram 2) OC curve 3) Histogram 4) Flowchart
Correct Answer: Flowchart
Explanation: A �owchart maps process sequence and decision paths, making delays, loops, and hando�s visible.
Question 3: A control plan should primarily identify
Choices:
1) key product and process characteristics, control methods, reaction plans, and responsibilities 2) employee vacation schedules 3) only �nal inspection steps 4) supplier advertising claims Correct Answer: key product and process characteristics, control methods, reaction plans, and responsibilities Explanation: A control plan links important characteristics to measurement or control methods, frequency, responsibility, and reaction plans throughout the process.Page 2
Question 4: A medical device feature could cause serious injury if it fails. During design planning, the characteristic should be treated primarily as
Choices:
1) an optional benchmark 2) a supplier convenience 3) a critical quality characteristic requiring heightened control 4) a cosmetic preference
Correct Answer: a critical quality characteristic requiring heightened control
Explanation: Characteristics linked to signi�cant safety or regulatory consequences are treated as critical and receive stronger design and control attention.
Question 5: In risk management, severity refers to
Choices:
1) the magnitude of the consequence if an event occurs 2) how easy the event is to detect only 3) how often the event occurs 4) the project schedule duration
Correct Answer: the magnitude of the consequence if an event occurs
Explanation: Severity describes the seriousness of the consequence or impact associated with a risk event.Page 3
