Document Summary
Chapter 9: eliminating rival plausible explanations: the experiment. Three research approaches: classic experiment, quasi-experimentation, case study analysis. The three share a common underlying logic involving eliminating rival plausible explanations to make reasonable inferences about causes and other processes. Each differ in the degree that they emphasize manipulative control or analytic control: manipulative control: the active and intentional manipulation of the setting by the researcher in order to manimize clarity of inference by ontrolling rival plausible explanations. Experimenter exerts control over every aspect of the setting: analytic control: one of the two general approaches to research that atttempts to make inferencees about causes. Superstitious behavior comes from causal attributions we make that may make us feel better but are unlikely to have any real causal effect: lucky ring. Experimentation begins when we recognize, create a situation that includes the phenomenon of interest to us.
