Question

The consistency with which a test measures what it is supposed to be measured is termed as:

• A. Objectivity
• B. Reliability
• C. Usability
• D. Validity

Answer 1

Answer:

B. Reliability

Reliability and validity are both about how well a method measures something.

• Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions).

• Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).
