Software Testing and Quality Control Questions
Which of the following is a way to improve the reliability of a test?
-
Use a larger sample size.
-
Use a more reliable test.
-
Use a more valid test.
-
All of the above
B
Correct answer
Explanation
The only way to improve the reliability of a test is to use a more reliable test. Using a larger sample size or a more valid test will not improve the reliability of a test.
Which of the following is NOT a type of reliability?
-
Test-retest reliability
-
Parallel-forms reliability
-
Split-half reliability
-
Content validity
D
Correct answer
Explanation
Content validity is a type of validity, not reliability.
What is the degree to which a test measures what it is supposed to measure called?
-
Reliability
-
Validity
-
Accuracy
-
Precision
B
Correct answer
Explanation
Validity is the degree to which a test measures what it is supposed to measure.
Which of the following is NOT a common technique for validating software requirements?
-
Reviews
-
Inspections
-
Prototyping
-
User acceptance testing
D
Correct answer
Explanation
User acceptance testing is a technique for verifying that the software system meets the user's needs, not for validating the requirements for the system.
Which type of reliability is most important for tests that are used to screen for disorders?
-
Test-retest reliability
-
Parallel-forms reliability
-
Internal consistency reliability
-
Inter-rater reliability
C
Correct answer
Explanation
Internal consistency reliability is most important for tests that are used to screen for disorders because it assesses the consistency of scores across different items on the same test, which is essential for ensuring that the test is measuring a single underlying construct.
Which type of reliability is most important for tests that are used to screen for disorders?
-
Test-retest reliability
-
Parallel-forms reliability
-

Inter-rater reliability
C
Correct answer
Explanation
Internal consistency reliability is most important for tests that are used to screen for disorders because it assesses the consistency of scores across different items on the same test, which is essential for ensuring that the test is measuring a single underlying construct.
Which of the following is NOT a common type of quality control inspection?
-
In-process inspection
-
Final inspection
-
Pre-shipment inspection
-
Post-shipment inspection
D
Correct answer
Explanation
Post-shipment inspection is not a common type of quality control inspection, as it is conducted after the product has been shipped to the customer.
Which standard organization is responsible for developing and publishing textile testing methods?
-
ASTM International (American Society for Testing and Materials)
-
ISO (International Organization for Standardization)
-
AATCC (American Association of Textile Chemists and Colorists)
-
All of the above.
D
Correct answer
Explanation
ASTM International, ISO, and AATCC are recognized organizations that establish and publish standardized methods for testing and evaluating textiles, ensuring consistency and reliability in textile testing practices worldwide.
In-process Quality Inspection is carried out:
-
Before the production process begins
-
During the production process
-
After the production process is completed
-
At random intervals during the production process
B
Correct answer
Explanation
In-process Quality Inspection is conducted during the production process to monitor the quality of products at various stages of manufacturing. This inspection helps identify and rectify any defects or deviations from the specified standards.
Which type of quality control inspection is conducted at random intervals during the production process?
-
Initial Quality Inspection
-
In-process Quality Inspection
-
Final Quality Inspection
-
Random Quality Inspection
D
Correct answer
Explanation
Random Quality Inspection is conducted at random intervals during the production process to ensure that the quality of products is consistent throughout the manufacturing process. This inspection helps identify any potential issues or defects that may arise during production.
Statistical Quality Control (SQC) involves the use of:
-
Sampling techniques
-
Inspection checklists
-
Visual inspection methods
-
Destructive testing methods
A
Correct answer
Explanation
Statistical Quality Control (SQC) involves the use of sampling techniques to evaluate the quality of a product or process. By analyzing a representative sample, SQC helps determine the overall quality level and identify any potential issues or defects.
Acceptance Sampling is a type of quality control inspection where:
-
All products are inspected
-
A sample of products is inspected
-
Destructive testing is performed
-
Statistical methods are used to evaluate quality
B
Correct answer
Explanation
Acceptance Sampling is a quality control inspection method where a sample of products is inspected to determine if the entire lot meets the specified quality standards. This method helps reduce inspection costs and allows for faster decision-making.
Which of the following is NOT a common type of Destructive Testing?
-
Tensile testing
-
Compression testing
-
Fatigue testing
-
Visual inspection
D
Correct answer
Explanation
Visual inspection is not a type of Destructive Testing. Destructive Testing involves subjecting a product or component to extreme conditions or forces to assess its durability and performance. Visual inspection is a non-destructive method used to identify defects or deviations from the specified standards.
Which of the following is a common quality control technique?
-
Sampling Inspection
-
100% Inspection
-
Statistical Process Control
-
All of the above
D
Correct answer
Explanation
Sampling Inspection, 100% Inspection, and Statistical Process Control are all common quality control techniques used to ensure product quality.
Which of the following is NOT a common type of environmental test for spacecraft?
-
Thermal vacuum testing
-
Vibration testing
-
Acoustic testing
-
Radiation testing
C
Correct answer
Explanation
Acoustic testing is not typically performed on spacecraft, as they are not exposed to significant acoustic loads during their missions. The other three types of tests are commonly conducted to assess the spacecraft's ability to withstand the harsh conditions of space.
