Question

Quizplus · Accepted Answer

The content validity ratio is calculated by dividing the number of experts who rated a test question as essential by the total number of experts who rated the question. This calculation provides evidence of the test's content validity, which is the degree to which the test measures the intended content or construct. The other options, such as calculating a correlation coefficient or mean rating, may be useful for other types of validity evidence but are not specifically related to content validity. A frequency table of ratings may be a useful tool for organizing and analyzing the expert ratings, but it does not in itself provide evidence of validity.
