Document Summary
Case study: brings together wide range of information, including interviews, observations, test scores, best used to study unique types of individuals, may be influenced by researcher biases, and findings may not generalize. Ethnography: participant observation of a culture or distinct social group, mix of observations, self-reports, interpretation by investigator, results can be biased by the researcher, findings are limited to the individuals and settings studied. Correlational design: researchers gather information and make no effort to alter participants" experiences, limited because cause and effect cannot be inferred. Independent: experimenter controls or manipulates, expected to cause changes in another variable, dependent, experimenter measures but does not manipulate, expected to be influenced by the independent variable. Modified experiments: field experiments, use rare opportunities for random assignment in natural settings, natural experiments, compare differences in treatment that already exist, groups chosen to match characteristics as much as possible.
