Document Summary
Bias is systematic measurement error as opposed to random measurement error. Therefore, test bias reduces validity for specific groups. Groups of people defined on a nominal basis (e. g. , race, sex, religion, etc. ) do not always show the same average level of performance on tests. Genetic may have something to do with differences in groups (e. g. , genetically, men are taller than women height is very heritable) However, genes rarely have a large impact on results. E. g. , you have the genetic potential to do well but the environment doesn"t activate your potential to do well. According to ctbh, group differences are believed to be the result of test bias and not the result of actual differences. The validity of the ctbh is one of the most crucial scientific questions facing psychology today. In terms of assessment, bias is a systematic influence that distorts measurement or prediction by test scores. It doesn"t change variability; it distorts the findings.
