Several psychological tests have been shown to have biases, which can be of different kinds, such as construct, method, or item bias. In a test that is biased, a certain group may get higher scores or a particular group may get lower scores. These biases may be rooted in culture, gender, race, socioeconomic status, career, education, and so on. Do research at your school library and online, and write about a psychological test that may have once been used extensively, but has been proven to be biased against or in favor of certain groups.
