Examination for Professional Practice of Psychology (EPPP) Practice Test

The Taylor-Russell tables are utilized to estimate the validity and utility of a selection test for employment or other selection decisions by considering how predictive the test is for successful job performance. The three key components needed to effectively use these tables are the base rate, selection ratio, and validity coefficient. The base rate refers to the proportion of current employees who are successful in their roles. The selection ratio is the number of applicants selected divided by the number of applicants who applied. The validity coefficient indicates how well the test predicts job performance based on empirical data. Together, these factors help determine the effectiveness of the selection process and the expected outcomes of using the test in terms of correctly identifying successful candidates. By understanding the relationship between these variables, practitioners can better anticipate the positive impact of employing a selection test on their hiring processes.
