EPPP- Design Under Scrutiny — Experimental Controls, Blinding, and Threats to Validity

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.
