Question

Quizplus · Accepted Answer

The reliability of a test can be assessed by measuring whether people get about the same score on repeated tests, which indicates consistency and stability of the test results over time. This can be done through statistical methods such as test-retest reliability, inter-rater reliability, or internal consistency reliability. The other options (A, C, and D) are not directly related to the concept of reliability but rather address other aspects such as accessibility, fairness, or validity of the test.
