Validity

A judgement of estimate of how well a test measure what it purports to measure

• Reliability

• Utility

• Validity

• Valid

measure the validity that is arrived at by executing a comprehensive analysis on how test can be relate and how test can be understood

• Construct validity

• Criterion-related validity

• Content Validity

• Norm-related validity

It is the weakest type of validity

• Ecological validity

• Content validity

• Face validity

• Umbrella validity

A. Valid test is always a reliable test..

B. But a reliable test is a necessarily valid

• both A and B are true

• A is false while B is true

• both A and B are false

• A is true while B is false

Type of Criterion-related validity that which test score is related to some criterion measure obtained at the same time.

• Predictive validity

• Construct validity

• Criterion

• Concurrent validity

Implies systematic variation in the test scores

• Factor analysis

• Criterion

• Bias

• Cost

All types of validity evidence, including evidence from content and criterion-related varieties of validity come under this type of validity

• Construct validity

• Concurrent validity

• Predictive validity

• Face validity

A. Ideally a criterion is a contaminated.

B. criterion contamination is the term applied to a criterion measure that has been base, at least in part of predictive measures.

• Both A and B are True

• A is true, while B is false

• A is false, while B is True

• Both A and B are False

A tendency to which a particular person give a higher rating in the reason of favorable impression

• Fairness

• Halo Effect

• Rating error

• Bias

A type of evidence under construct validity which scores on the test should not theoretically be collerated

• Evidence of pretest/posttest changes

• Convergent evidence

• Evidence of changes with age

• Discriminant evidence
