Concurrent validity
Which type of validity is used when the criterion variables are measured after the scores of the test?
High predictive validity
What type of validity is the extent to which measures of the same or similar constructs actually correspond to each other?

Study Notes
Validity
- Validity refers to the extent to which a test or measurement accurately measures what it claims to measure.
Types of Validity
- Face Validity: refers to the extent to which a test appears to measure what it claims to measure based on face value.
- Construct Validity: refers to the extent to which a test measures the underlying concept or construct being measured.
Types of Validity (continued)
- Content Validity: refers to the extent to which the measurement covers all aspects of the concept being measured.
- Criterion Validity: refers to the extent to which a test accurately predicts future behavior or outcomes.
Evaluating Validity
- Concurrent Validity: evaluates how accurately a test measures the outcome it was designed to measure, and the scores of the test and the criterion variables are obtained at the same time.
- Predictive Validity: evaluates how accurately a test predicts future outcomes, and the criterion variables are measured after the scores of the test.
Inter-Method Validity
- Convergent Validity: refers to the extent to which measures of the same or similar constructs actually correspond to each other.
- Discriminant Validity: shows that two measures that are not supposed to be related are in fact, unrelated.
Face Validity
- Face validity assesses whether a test appears to measure what it claims to measure based on face value.
This quiz covers the concepts of validity and reliability in measurement. It explains the degree to which an instrument measures what it intends to measure or how accurately a method assesses a particular attribute. Examples are provided to aid comprehension.
