Which statement(s) out of the following is/are true :

(A) A valid test will also be reliable as well

(B) A reliable test will also be valid always

(C) A valid test may be or may not be reliable

(D) A reliable test may be or may not be valid

(E) There is no relation between reliability and validity of a test

Choose the correct answer from the options given below : 

The correct answer is - (A) and (D) Only

Key Points

• A valid test will also be reliable as well
  • A test that is valid effectively measures what it is supposed to measure.
  • If a test is valid, it will consistently measure the intended construct, making it also reliable.
• A reliable test may be or may not be valid
  • A test that is reliable provides consistent results.
  • However, a reliable test does not guarantee that it measures what it is supposed to measure, hence it might not be valid.

Additional Information

• Reliability
  • Reliability refers to the consistency of a test or measurement.
  • It is measured through various methods such as test-retest, inter-rater, and internal consistency.
• Validity
  • Validity refers to how well a test measures what it is intended to measure.
  • Types of validity include content validity, criterion-related validity, and construct validity.
• The Relationship Between Reliability and Validity
  • While a valid test is usually reliable, a reliable test might not always be valid.
  • Understanding both concepts is crucial for developing effective assessments and measurements.
