PSYC1003 Lecture Notes - Lecture 1: Operational Definition, Psych, Dependent And Independent Variables
Document Summary
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. ) Description develop measurement techniques that describe behavior clearly and precisely. ii. 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. iii. 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. Step 2: select research method & define study. 2 a b c a b c d e f g h i j k l m n o p q r a b a. Empirical knowledge should be acquired through observation.
