MEASUREMENT FINAL PRACTICE
EXAM QUESTIONS WITH CORRECT
ANSWERS 100% VERIFIED.
1. In the context of Quality Management Systems, what does the ‘PDCA’ cycle represent?
A. Produce, Deliver, Check, Act
B. Plan, Design, Correct, Assess
C. Process, Design, Control, Analyze
D. Plan, Do, Check, Act
Answer: D
Conceptual Explanation: PDCA stands for Plan-Do-Check-Act, a four-step model for
carrying out change and continuous improvement.
2. Which quality tool is used to identify the ‘vital few’ problems versus the ‘useful many’?
A. Pareto Chart
B. Histogram
C. Scatter Diagram
D. Control Chart
,Answer: A
Conceptual Explanation: The Pareto Chart is based on the 80/20 rule, helping to
prioritize problems that have the greatest impact.
3. What is the primary difference between precision and accuracy in measurement?
A. Accuracy refers to consistency; precision refers to proximity to the true value.
B. Accuracy refers to proximity to the true value; precision refers to the consistency of
repeated measurements.
C. Precision refers to the smallest unit of measure; accuracy refers to the range.
D. There is no difference in a manufacturing context.
Answer: B
Conceptual Explanation: Accuracy is how close a measurement is to the true value, while
precision is how close measurements are to each other.
4. Which of the following is considered ‘Attribute Data’?
A. The number of scratches on a finished surface
B. The weight of a chemical batch in kilograms
C. The length of a steel rod in millimeters
D. The temperature of a furnace in degrees Celsius
Answer: A
, Conceptual Explanation: Attribute data is counted (pass/fail, go/no-go, number of
defects), whereas variable data is measured on a continuous scale.
5. If a process is ‘In Control’ according to a control chart, it means:
A. There are no defects being produced.
B. The process is meeting all customer specifications.
C. Only common cause variation is present.
D. The process is running at maximum speed.
Answer: C
Conceptual Explanation: A process is in statistical control when only inherent, common
cause variation exists, and no special causes are detected.
6. What is the main purpose of a ‘Go/No-Go’ gauge?
A. To provide an exact numerical measurement of a part.
B. To calibrate micrometers and calipers.
C. To check if a part falls within specified tolerance limits quickly.
D. To measure the surface roughness of a machined part.
Answer: C
Conceptual Explanation: Go/No-Go gauges are fixed-limit tools used to quickly determine
if a dimension is within the acceptable range without providing a specific value.
