Document Summary
Basics of social research - chapter 9: give three characteristics of research questions that are appropriate to be tested using the experimenter method. Isolate and target the impact of one/a few causal variables. Ethical/practical limitations: describe the three steps used in the process of random assignment. Devise a method to randomize (purely mechanical). Assign subjects to control and experimental groups: describe the seven parts of an experiment. Random assignment: describe how the experimental method can meet the three criteria of causality, explain how the classical experimental design compares with the five other major designs in terms of their major components. A classical experimental design includes random assignment, a pretest, a post-test, an experimental group, and a control group. Three criteria: temporal order, association, elimination of plausible alternatives. The classical experimental design used a pretest and post-test to account for temporal order, experimental group to account for association, and control group to account for elimination of plausible alternatives.
