Question

Quizplus · Accepted Answer

A measure's validity can vary depending on the purpose for which it is being used. For example, a test may be highly valid for measuring math skills but have low validity for measuring social skills. Therefore, statement A is true. Statement B is incorrect because there can be varying degrees of validity, with some measures being more or less valid than others. Statement C is also incorrect because all types of validity are related to each other, as they are all concerned with whether a measure is actually measuring what it is intended to measure. Statement D is incorrect because validity can be assessed through indirect evidence as well, such as examining the measure's consistency with other measures.
