A test cannot be deemed reliable without having established validity.

Question

Quizplus · Accepted Answer

Reliability refers to the consistency of a measure (a test is reliable if it consistently produces the same results under the same conditions), while validity refers to the accuracy of a measure (a test is valid if it measures what it is supposed to measure). A test can be reliable without being valid; reliability is a prerequisite for validity, but a test can consistently measure something consistently (reliable) without measuring what it's supposed to measure (valid).
