Question

Quizplus · Accepted Answer

Criterion-related evidence of validity is demonstrated through methods that show a test's scores are correlated with an external criterion. The expectancy table is a tool used to illustrate how well test scores predict outcomes, such as job performance or academic success, making it relevant for showing criterion-related validity. The alpha coefficient and the Spearman-Brown formula are related to reliability, not validity.
