Validity and its type ( Educational Research)

Validity and its type ( Educational Research)

Concept of validity given by Kelly (1927) and defined validity as “a test is valid if it measures what it claims to measure”.
Logically, validity is the property of an argument made up of on the fact- ‘the truth of the hypotheses, guarantees the truth of the conclusion’.
• Construct validity: Does the test measure the concept that it’s intended to measure?
• Content validity: Is the test fully representative of what it aims to measure?
• Face validity: Does the content of the test appear to be suitable to its aims?
• Criterion validity: Do the results accurately measure the concrete outcome they are designed to measure?
