The Hawthorne effect, which refers to the phenomenon where participants alter their behavior simply because they are being observed or they know they are part of an experiment, is typically associated with experimental designs. Quasi-experiments are designed to address research questions in settings where experimental control is difficult or impossible, such as in the study of naturally occurring events or when manipulating variables is ethically or practically prohibited. Therefore, quasi-experiments generally do not involve the same level of experimental effects as standard experiments.
