Education QUESTION #6759
Question 1
A test is highly reliable but consistently measures vocabulary skill instead of reading comprehension as intended. According to the framework of validity and reliability, which statement is MOST accurate?
  • The test is both valid and reliable because reliability is the most important psychometric property
  • The test is reliable but not valid for its intended purpose; reliability is necessary but not sufficient for validity✔️
  • The test is valid because it consistently measures something — consistency itself defines validity
  • Both validity and reliability are compromised when the construct measured differs from the intended one
Correct Answer Explanation
This scenario illustrates the classic principle: a test can be reliable without being valid. Reliability (consistency) is a necessary but not sufficient condition for validity. Valid results require that the test measures what it claims to measure. Consistent measurement of the wrong construct produces reliable but invalid scores.
