Document Summary
The scientific method is a system of rules for investigation that can be used in many disciplines. Theory: a set of standards that describe a relation between behavior and the factors that influence that behavior theory is a set of statements describing the relation between a phenomenon and the factors assumed to influence it. A theory supported by considerable research evidence is a law or principle, Hypothesis: a statement as to how one variable(s) may influence another variable(s, example: high temperature conditions enhance aggression, hypothesis postulates an as yet unsubstantiated relationship that will be tested in an experimental investigation. Law (principale: a proven statement supported by strong evidence, responses that produce satisfying consequences are strengthened (law of effect) The scientific method assumes objective measurement: serves to eliminate bias, aims to operationalize the methods of study so that other scientists can replicate the study (and presumably replicate the research findings)
