Confidentiality

Anonymity
Debriefing

One major reason quasi-experimental designs are often seen as having diminished strength is their lack of random assignment, which can lead to difficulty in asserting causal relationships. This method is frequently used when ethical or practical considerations make random assignment unfeasible, like in educational studies. Scholars often find themselves employing statistical techniques to control for pre-existing differences instead.

When it comes to ethical practices, informed consent is paramount! Researchers must not only inform participants about the nature of the study but also ensure they understand the risks and benefits involved. This fosters trust and respect, ensuring participants contribute willingly to the research while being fully aware of its true purpose and scope.
