What is ex post facto research with examples?
The assignment of subjects to different groups is based on whichever variable is of interest to the researchers. For example, a researcher is interested in how weight influences self-esteem levels in adults. This is an ex post facto design because a pre-existing characteristic (weight) was used to form the groups.
What is the difference between experimental and ex post facto research?
True experiments have random assignment because you’re looking at something else. In ex post facto, you are looking at a prior variable present in the participant. In an ex post facto design, you are not randomly assigning people to an experimental group or control group.
How do you carry out Expost facto research?
Isaac and Michael (1971) established the sequence of steps involved in ex post facto research, and it should include:
- Define the problem.
- Examine the literature.
- State the hypotheses.
- List the assumptions on which the assumptions are based and the procedures will be based.
- Design the approach:

Two other forms of quantitative research, which are not experimental due to lack of manipulation, are ex post facto (sometimes called causal-comparative) and correlational. Often both of these types are grouped into what researchers call non-experimental research or simply correlational research.
