There could be real mean differences in the attributes being measured between different groups, which could lead to different scores on tests. Additionally, the content of the test may be more familiar to certain groups based on their experiences, educational background, or cultural norms, which could also contribute to systematic score differences. Finally, the manner in which a test is presented (e.g. language used, format, instructions given) could vary between groups and contribute to different performance outcomes.
