EXAM QUESTIONS WITH CORRECT
ANSWERS 100% VERIFIED.
1. What is the primary objective of using a Pareto Chart in quality control?
A. To identify the relationship between two variables
B. To track the progress of a project over time
C. To identify the ‘vital few’ problems that account for the majority of quality issues
D. To document the standard operating procedures
Answer: C
Conceptual Explanation: The Pareto principle (80/20 rule) states that roughly 80% of
effects come from 20% of causes. A Pareto Chart helps prioritize which problems to solve
first.
2. In Statistical Process Control (SPC), what does a ‘Cpk’ index of less than 1.0 indicate?
A. The process is highly capable and centered
B. The measurement system is inaccurate
C. The process variation is within the control limits
D. The process is not capable of meeting design specifications
,Answer: D
Conceptual Explanation: A Cpk value less than 1.0 indicates that the process variation is
wider than the specification width or the process is significantly off-center, meaning it will
produce non-conforming parts.
3. Which measurement tool is most appropriate for measuring a bore with a tolerance of +/-
0.0001 inches?
A. Digital Caliper
B. Bore Gauge with a high-precision dial indicator
C. Steel Rule
D. Tape Measure
Answer: B
Conceptual Explanation: Calipers are generally accurate to 0.001 inches. For tolerances in
the ten-thousandths (0.0001), a specialized bore gauge or air gauge is required.
4. What is the fundamental difference between ‘Accuracy’ and ‘Precision’?
A. Accuracy refers to being close to the true value, while precision refers to the
repeatability of measurements
B. Accuracy refers to consistency, while precision refers to being close to the target
C. They are the same in industrial metrology
D. Precision is only measured in metric units
, Answer: A
Conceptual Explanation: Accuracy is the degree of closeness to the true value; precision is
the degree to which repeated measurements under unchanged conditions show the same
results.
5. Which of the following is considered a ‘special cause’ of variation in a manufacturing
process?
A. A dull cutting tool
B. Ambient humidity changes
C. Minor fluctuations in raw material composition
D. Normal machine vibration
Answer: A
Conceptual Explanation: Special causes (assignable causes) are not inherent in the
process and can be identified and removed, such as a broken tool or operator error.
Common causes are inherent to the system.
6. In the PDCA cycle of continuous improvement, what does the ‘A’ stand for?
A. Analyze
B. Act
C. Adjust
D. Assess
