Defining Psychological Science: The Experimental Method

This AP Psychology study guide covers research methods, including basic vs. applied research, the scientific method (theory, hypothesis, and operational definitions), and variables (independent, dependent, confounding, and control). It also discusses the Hawthorne effect, establishing cause and effect through random assignment, sampling bias and experimenter bias, and common sense biases (hindsight bias, overconfidence, and perceiving order in random events).
