Document Summary
Three sets of interrelated goals: measurement and description, understanding and prediction, and application and control. 1: develop measurement techniques that make it possible to describe behaviour clearly and precisely. 1: explain the reasons for the occurrence of the events. Hypothesis about physiological arousal affecting emotions variables would be physiological arousal and emotional state. Hypothesis: tentative statement about the relationship between two or more variables. Variables: any measurable conditions, events, characteristics, or behaviours that are controlled or observed in a study. 1: practical problems and how to control them. Theory: a system of interrelated ideas used to explain a set of observations. Step 1: formulate a testable hypothesis: hypothesis expressed as a prediction, must be formulated precisely, and the variables under study must be clearly defined. Researchers achieve these clear formulations by providing operational definitions of the relevant variables. Operational definition: describes the actions or operations that will be used to measure or control a variable.
