EPPP- Design Under Scrutiny — Experimental Controls, Blinding, and Threats to Validity
About this episode
This episode explores key experimental design concepts relevant to the EPPP, focusing on threats to validity and practical psychology examples.
This episode breaks down the experimental design content the EPPP loves to test — independent and dependent variables, randomization, blinding, and the specialized designs like Solomon Four-Group and Latin Square. We walk through every threat to internal validity, from history to regression to the mean, and translate each one into a real psychology example you can hold onto in the exam room. This is clarity of thinking, not memorization, built one design element at a time.
