Choose the correct answer from the options given below:

Correct option is C

Reliability and validity are related but distinct concepts in educational testing:

• Reliability refers to the consistency of a test's results.
• Validity refers to whether the test measures what it is intended to measure.

A test can be valid but not reliable, but for a test to be truly valid, it must first be reliable.

Information Booster:

• Reliability can be tested through methods like test-retest and inter-rater reliability.
• Validity is categorized into construct validity, content validity, and criterion-related validity.

Additional Knowledge:

• In educational settings, it's crucial that both validity and reliability are considered to ensure fair and accurate assessments.
