Assignment bias happens when experimental groups have significantly different characteristics due to a faulty assignment process.For example, if you’re performing a set of intelligence tests, one group might have more people who are significantly smarter. Although this type of bias is usually associated with non-random sampling and assignment, it c...
Random assignment can help to control assignment bias by ensuring that treatment groups and control groups have an equal spread of characteristics. That said, random assignment is not always possible, especially in the medical fields where it may be unethical to assign patients to control groups. If you are unable to use random samplingand random a...
Assignment bias can be a threat to internal validity, because it allows two different explanations for differences in treatment results. For example, if you find that a weight loss procedure results in weight loss of more than 50 lbs, it could be that the treatment is actually effective, or it could be that the differences are because people in the...
