MSSC QUALITY PRACTICES &
MEASUREMENT PRACTICE EXAM
QUESTIONS WITH CORRECT ANSWERS
100% VERIFIED.
1. Which statistical tool is primarily used to identify the ‘vital few’ causes of problems from
the ‘trivial many’?
A. Control Chart
B. Pareto Diagram
C. Histogram
D. Scatter Plot
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 possible causes, allowing teams to
prioritize improvements.
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 is meeting all customer specifications
,D. The process is centered perfectly but has high spread
Answer: B
Conceptual Explanation: A Cpk of less than 1.0 indicates that the process spread is wider
than the specification limits or the mean is too close to a limit, meaning it will produce non-
conforming parts.
3. Which dimensioning system uses a symbolic language to communicate how a part should
be manufactured and inspected based on its function?
A. Metric System
B. Geometric Dimensioning and Tolerancing (GD&T)
C. Coordinate Dimensioning
D. Architectural Scaling
Answer: B
Conceptual Explanation: GD&T is a precise language used on engineering drawings to
define the allowable variation in form, orientation, and location of part features.
4. What is the primary purpose of a Gage R&R (Repeatability and Reproducibility) study?
A. To calibrate the tool against a national standard
B. To increase the speed of the inspection process
C. To determine the amount of variation in the measurement system
D. To eliminate the need for manual inspection
, Answer: C
Conceptual Explanation: Gage R&R evaluates whether a measurement system’s variation
is acceptable compared to the process variation or specification limits.
5. Which of the following describes ‘Accuracy’ in measurement?
A. How close measurements are to each other
B. The smallest unit a tool can measure
C. The range of the measurement tool
D. How close a measurement is to the true value
Answer: D
Conceptual Explanation: Accuracy refers to the closeness of agreement between a
measured value and a standard or true value, whereas precision refers to consistency.
6. A ‘Poka-Yoke’ is a mechanism used in lean manufacturing for what purpose?
A. Just-in-time delivery
B. Mistake-proofing a process
C. Inventory tracking
D. Increasing machine speed
Answer: B
