MEASUREMENT FINAL EXAM PREP
QUESTIONS WITH CORRECT ANSWERS
100% VERIFIED.
1. A process is considered in ‘statistical control’ when variation is caused by which of the
following?
A. Common causes only
B. Special causes only
C. Assignable causes only
D. Both special and common causes
Answer: A
Conceptual Explanation: Statistical control means that the process is stable and only
natural, inherent ‘common cause’ variation is present. Special causes indicate an out-of-
control condition.
2. Which quality tool is used to identify the ‘vital few’ problems compared to the ‘useful
many’?
A. Histogram
B. Control Chart
,C. Pareto Chart
D. Fishbone Diagram
Answer: C
Conceptual Explanation: The Pareto Chart is based on the 80/20 rule, helping teams focus
on the 20% of causes that result in 80% of the problems.
3. If a dial caliper has a resolution of 0.001 inches, what is the smallest measurement it can
reliably indicate?
A. 0.001 inches
B. 0.0001 inches
C. 0.01 inches
D. 0.1 inches
Answer: A
Conceptual Explanation: Resolution refers to the smallest increment a tool can detect or
display; in this case, 0.001 inches.
4. What is the primary purpose of a Gauge R&R study?
A. To determine the variation in the measurement system
B. To check if a part meets specifications
C. To calibrate the tool to a master standard
, D. To calculate the process capability index
Answer: A
Conceptual Explanation: Gauge Repeatability and Reproducibility (R&R) studies evaluate
how much of the total observed process variation is due to the measurement system itself.
5. In a Lean manufacturing environment, what does the term ‘Poka-Yoke’ refer to?
A. Continuous improvement
B. Leveling production
C. Visual management
D. Mistake-proofing
Answer: D
Conceptual Explanation: Poka-Yoke is a technique for avoiding simple human errors by
designing the process or equipment so that the error cannot occur or is immediately
obvious.
6. Which measurement tool is best suited for measuring the diameter of a deep, narrow
hole?
A. Telescoping Gauge
B. Outside Micrometer
C. Feeler Gauge
D. Depth Micrometer
