Document Summary
Chapter 2 - the research enterprise in psychology. Goals of the scieniic enterprise: measurement and descripion. Igure out a way to measure the phenomenon under study. Develop measurement techniques that make it possible to describe behaviour clearly and precisely: understanding and predicion. Hypothesis: a tentaive statement about the relaionship between two or more variables. Variables: are any measureable condiions, events, characterisics, or behaviours that are controlled or observed in a study: applicaion and control. Theories permit psychologists to make leap from the descripion of behaviour to the understanding of behaviour. Conidence in a theory increases when hypotheses derived from it are supported by research. Scienists use operaional deiniions to clarify what their variables mean. Operaional deiniions: describes the acions or operaions that will be used to measure or control a variable. Select the research method and design the study. Paricipants: persons or animals whose behavior is systemaically observed in a study: collect the data.
