MSSC QUALITY PRACTICES &
MEASUREMENT FINAL EXAM
QUESTIONS WITH CORRECT ANSWERS
100% VERIFIED.
1. Which international standard series provides the framework for a comprehensive quality
management system?
A. ISO 14000
B. OSHA 1910
C. ISO 9000
D. ANSI Z540
Answer: C
Conceptual Explanation: The ISO 9000 series is the international standard for quality
management and quality assurance, focusing on meeting customer requirements and
improving quality.
2. What is the primary purpose of a Pareto chart in quality control?
A. To identify the most frequent causes of defects (the ‘vital few’)
B. To show the relationship between two variables
C. To track the progress of a project over time
,D. To determine if a process is within statistical control
Answer: A
Conceptual Explanation: A Pareto chart is a bar graph used to identify the most
significant factors in a data set, following the 80/20 rule where 80% of problems come
from 20% of causes.
3. Which measurement tool is most appropriate for measuring the depth of a blind hole with
high precision?
A. Steel rule
B. Depth micrometer
C. Telescoping gauge
D. Outside calipers
Answer: B
Conceptual Explanation: A depth micrometer is specifically designed to provide precise
measurements of the depth of holes, slots, and recesses.
4. In Statistical Process Control (SPC), what does the term ‘out of control’ signify?
A. The process is influenced by special cause variation
B. The process is no longer meeting customer specifications
C. The parts are all scrap
D. The operator is not following the procedure
, Answer: A
Conceptual Explanation: A process is ‘out of control’ when identifiable, non-random
‘special causes’ affect the process, even if the parts are still within tolerance limits.
5. What is the standard measurement unit for surface roughness in the United States?
A. Micro-inches (Ra)
B. Millimeters
C. Decibels
D. Centimeters
Answer: A
Conceptual Explanation: Surface roughness is typically measured in micro-inches (Ra) in
the U.S. customary system, representing the arithmetic average of profile height deviations.
6. Which of the following describes the difference between the measured value and the true
value?
A. Precision
B. Resolution
C. Accuracy
D. Repeatability
Answer: C
