Putting it simply, it is a law passed after someone has committed some legal act until said law was passed, making it illegal. So if you're testing a new type of medication, the experimental group gets the new medication, while the control group gets the old medication.

Generally this is not considered ex post facto law even though it is clearly extremely destructive to economic stability and progress. Although differing groups are analyzed and compared in regards to independent and dependent variables it is not a true experiment because it lacks random assignment. While both designs are non-experimental. The point of interest to us is that in identifying the causes retrospectively, the expert adopts an ex post facto perspective. Chi-square is used when the level of measurement of the variables is nominal Salkind, 2010. Judicial review and ex post facto laws fall into two different categories.
