Question

If a person scores a 70 on an intelligence test on one day and scores 110 when retested on another day, you might conclude that this test is ________.

A) valid
B) invalid
C) reliable
D) unreliable
E) consistent

Answer 1

The correct answer is 'reliable'. If a person scores differently on the same test given on different days, the test is unreliable and not valid for measuring intelligence.

Step-by-step explanation:

The correct answer to the question is C) reliable. If a person scores a 70 on an intelligence test on one day and scores 110 when retested on another day, it indicates that the test is generating consistent and reliable results. Test-retest reliability is a type of reliability that refers to the consistency of test scores over time. In this case, the test is producing different scores on different occasions, suggesting that it is not valid as it is not accurately measuring the person's intelligence.
