Random assignment (RA)– into groups eliminate other possible explanations for results How is it different from random sampling (RS)…? Experimental Methods: how are these used? About 3/4ths of Social Psych research.

Less often, social psych uses correlational studies What is examined? 2 distinguishing factors of true experiments: (Table 1.1) 1. Control & manipulation of variables 2. Random assignment to groups – What is its benefit?

Example of a social psych experiment – In experiments, use IVs and DVs Independent variables (IV): what is manipulated Example? Dependent variables (DV): observed to determine impact of IV

External validity – questions related to whether results will generalize Depends on: Mundane realism & Experimental realism (read about these on p. 27 in text)

Ethics & Deception IRB protects participants Types of deception: How? 1) False Purpose 2) False Feedback 3) Use of a confederate/actor Benefits of deception? Ethical concerns?
