1. What is the primary purpose of quality control in manufacturing?
A. Increase production speed
B. Reduce workforce size
C. Ensure products meet required standards
D. Eliminate all inspections
Correct Answer: C
Rationale: Quality control ensures that products meet specified standards and
customer requirements before release.
2. Which tool is commonly used to measure internal diameters?
A. Vernier caliper
B. Bore gauge
C. Micrometer screw gauge
D. Steel rule
Correct Answer: B
Rationale: A bore gauge is specifically designed to measure internal diameters
accurately.
3. What does ISO 9001 primarily focus on?
,A. Financial auditing
B. Quality management systems
C. Machine maintenance
D. Workforce training
Correct Answer: B
Rationale: ISO 9001 sets requirements for quality management systems to ensure
consistent product quality.
4. Which of the following is a variable measurement?
A. Pass/fail inspection
B. Color classification
C. Length in millimeters
D. Defect count
Correct Answer: C
Rationale: Variable measurements are numerical and continuous, such as length
or weight.
5. What is the main goal of Statistical Process Control (SPC)?
A. Increase production costs
B. Monitor and control process variation
C. Replace quality inspectors
D. Eliminate documentation
Correct Answer: B
Rationale: SPC uses statistical methods to monitor and reduce process variation.
6. Which chart is commonly used in SPC for defect counts?
A. X-bar chart
B. Pareto chart
,C. p-chart
D. Scatter plot
Correct Answer: C
Rationale: p-charts are used for monitoring proportion of defects in a sample.
7. What does a “defect” refer to in quality control?

Rationale: A micrometer provides high precision for small measurements.
9. What is tolerance in manufacturing?
A. Maximum production speed
B. Allowed variation in a dimension
C. Total product cost
D. Machine efficiency level
, Correct Answer: B
Rationale: Tolerance defines acceptable limits of variation in a product dimension.
10. Which of the following is a sampling method?
A. Random sampling
B. Total inspection
C. Continuous production
D. Process automation
Correct Answer: A
Rationale: Random sampling selects units randomly for inspection to represent the
whole batch.
11. What does a Pareto chart help identify?
A. Machine efficiency
B. Major causes of defects
C. Employee performance
D. Production speed
Correct Answer: B
Rationale: Pareto charts highlight the most significant causes of problems.
12. Which is an attribute measurement?
A. Weight
B. Length
C. Pass/fail inspection
D. Temperature
Correct Answer: C
Rationale: Attribute data is categorical, such as pass/fail or defect/no defect.
