Document Summary
Review the scientific method (example: what are the five steps in the scientific method?) Review the different types of research approach (example: experimental, correlational, case study, surveys, etc. ) Review the purpose of using statistics in research. The scientific approach assumes that events are governed by laws. Psychologists assume behavior is governed by laws. (like the earth is governed by the law of gravity. ) Measurement & description develop measurement techniques that describe behavior clearly and precisely. Understanding & prediction make and test predictions called hypothesis. Hypothesis statements about the relationship between two or more variables. Variables any measurable characteristics or behaviors that are controlled or observed in a study. Application & control apply research findings to help practical problems. Theory the system of related ideas used to explain a set of observations. Scientific hypothesis must be formulated precisely, and variables under study must be clearly defined. Operational definition describes the action or operation used to measure or control a variable.
