Theory: a system of interrelated ideas used to explain a set of observations. Steps in a scientific investigation: scientific investigations are systematic, step 1: formulate a testable hypothesis. Variables under study must be clearly defined. Operational definition: describes the actions or operations that will be used to measure or control a variable: step 2: select the research method & design the study. Figure out how to put the hypothesis to an empirical test. Research method chosen depends on the nature of the question under study. Participants/subjects: persons or animals whose behavior is systematically observed in a study: step 3: collect the data.
