1. What is the primary objective of quality engineering?
A. Increase inspection activities
B. Eliminate all production employees
C. Reduce variation and improve process performance
D. Increase product complexity
Answer: C. Reduce variation and improve process performance
Rationale: Quality engineering focuses on controlling variation,
preventing defects, and improving processes and products.
2. Which quality guru is most closely associated with the PDCA
cycle?
A. Joseph Juran
B. W. Edwards Deming
C. Philip Crosby
D. Kaoru Ishikawa
Answer: B. W. Edwards Deming
Rationale: Deming promoted the Plan-Do-Check-Act cycle as a
systematic approach to improvement.
,3. Which statement best defines quality?
A. The highest possible production rate
B. Conformance to requirements and suitability for use
C. The most expensive product
D. Zero manufacturing cost
Answer: B. Conformance to requirements and suitability for
use
Rationale: Quality involves meeting specified requirements and
satisfying customer needs.
4. Which tool is commonly used to identify the possible causes
of a problem?
A. Fishbone diagram
B. Histogram
C. Control chart
D. Scatter plot
Answer: A. Fishbone diagram
Rationale: A fishbone or cause-and-effect diagram organizes
potential causes into logical categories.
5. What does the Pareto principle generally suggest?
A. All causes have equal importance
B. A small number of causes often account for a large
proportion of problems
,C. Inspection eliminates variation
D. Every process must have six sigma capability
Answer: B. A small number of causes often account for a large
proportion of problems
Rationale: Pareto analysis helps prioritize the vital few causes
that contribute most to an effect.
6. Which chart is most appropriate for displaying the
distribution of continuous measurements?
A. Histogram
B. Pareto chart
C. Flowchart
D. Check sheet
Answer: A. Histogram
Rationale: A histogram displays the frequency distribution of
measured data.
7. What is the main purpose of a check sheet?
A. Predict equipment life
B. Collect and organize data consistently
C. Calculate process capability
D. Determine engineering specifications
, Answer: B. Collect and organize data consistently
Rationale: Check sheets provide a structured method for
collecting data at the source.
8. Which statistic measures the arithmetic average of a data
set?
A. Median
B. Mode
C. Mean
D. Range
Answer: C. Mean
Rationale: The mean is calculated by adding all observations
and dividing by the number of observations.
9. Which measure represents the middle value when
observations are arranged in order?
A. Mean
B. Median
C. Variance
D. Standard deviation
Answer: B. Median
Rationale: The median divides an ordered data set into two
equal halves.
