AP PSYCHOLOGY

Detailed explanation-1: -Validity, often called construct validity, refers to the extent to which a measure adequately represents the underlying construct that it is supposed to measure.

Detailed explanation-2: -Measurement validity is the extent to which the data or results of a research method represent the intended variable. Valid results display accuracy in research methods and results. It’s important for methods and results to have validity so the research results can be useful and applied in various settings.

Detailed explanation-3: -Validity refers to how accurately a method measures what it is intended to measure. If research has high validity, that means it produces results that correspond to real properties, characteristics, and variations in the physical or social world. High reliability is one indicator that a measurement is valid.

Detailed explanation-4: -Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).

Detailed explanation-5: -What is criterion validity? To evaluate criterion validity, you calculate the correlation between the results of your measurement and the results of the criterion measurement. If there is a high correlation, this gives a good indication that your test is measuring what it intends to measure.
