MSSC QUALITY PRACTICES &
MEASUREMENT EXAM PREP
QUESTIONS WITH CORRECT ANSWERS
100% VERIFIED.
1. Which quality tool is most effective for identifying the ‘vital few’ problems compared to
the ‘useful many’?
A. Control Chart
B. Pareto Diagram
C. Fishbone Diagram
D. Histogram
Answer: B
Conceptual Explanation: The Pareto Diagram is based on the 80/20 rule, which suggests
that 80% of problems are caused by 20% of the causes, helping teams focus on the most
significant issues.
2. In Statistical Process Control (SPC), what does a ‘Cpk’ value of less than 1.0 indicate?
A. The process is highly capable
B. The process is not capable of meeting specifications
C. The process mean is perfectly centered
,D. The process variation is zero
Answer: B
Conceptual Explanation: A Cpk of less than 1.0 means the process spread is wider than
the specification width or the mean is too close to a limit, indicating the process cannot
consistently meet requirements.
3. What is the primary function of a Go/No-Go plug gauge?
A. To measure the exact diameter of a hole
B. To determine the roundness of a shaft
C. To measure the surface roughness of a bore
D. To check if a hole is within specific tolerance limits
Answer: D
Conceptual Explanation: Go/No-Go gauges are attribute measurement tools used to
quickly verify if a part feature is within the upper and lower tolerance limits without
providing a numerical value.
4. Which ISO standard specifically addresses the requirements for a Quality Management
System?
A. ISO 9001
B. ISO 45001
C. ISO 14001
, D. ISO 17025
Answer: A
Conceptual Explanation: ISO 9001 is the international standard that specifies
requirements for a quality management system (QMS) to demonstrate the ability to
consistently provide products and services.
5. When using a standard 0-1 inch micrometer, what distance does one full revolution of the
thimble represent?
A. 0.025 inch
B. 0.050 inch
C. 0.100 inch
D. 0.001 inch
Answer: A
Conceptual Explanation: On a standard English micrometer, the screw thread has 40
threads per inch, so one full turn moves the spindle 1/40th of an inch, which equals 0.025
inches.
6. What is the first step in the PDCA cycle?
A. Plan
B. Process
C. Perform
