Experimental method (causal: components of experimental research: Independent variable (manipulate: random allocation of subjects usually occurs, dependent variable (measure that depends on the manipulation, experimental group (gets treatment, control group (no treatment, random assignment (critical to groups, main effects: variable causes change in dv. Interactions: independent variables combine to produce an effect (this is common) Involves categorical variables in which subjects belong to but are not randomly allocated such as being diabetic or not: cannot control all variables --> noise or also known as confounding variables. Random clinical trial studies: participants are randomly assigned to treatment conditions.
