Checking consistency between two halves of one test is split-half reliability.
Is this answer helpful and correct?
0 agree0 disagree
Consistency alone does not guarantee validity: a test can consistently measure the wrong construct, so it is reliable but may lack validity.
Is this answer helpful and correct?
0 agree0 disagree
Measuring an unintended construct consistently is reliable but not valid, which separates the two concepts.
