According to the authors stated that for psychometricians the term bias “is a factor inherent in a test that systematically prevents accurate, impartial measurement” (Cohen & Swerdlik, 2018, p. 192). Furthermore, the authors stated that the term bias suggests systematic variation (Cohen & Swerdlik, 2018). According to the text, a test is deemed bias if a portion of its variances derives from factors that are unrelated to the performance on the criterion being measured; subsequently, a group of test takers will have performed differently than another (Cohen & Swerdlik, 2018). Thus, the others stated that some tests are found to be bias based on the design research study instead of the design of the test (Cohen & Swerdlik, 2018).
