PSY 230 Lecture 13: Chapter 13 Vocab (Cerego)
Document Summary
Quasi-experiment: a study that is similar to an experiment except that the researchers do not have full experimental control (e. g. , they may not be able to randomly assign participants to the independent variable conditions). Nonequivalent control group design: an independent-groups quasi-experiment that has at least one treatment group and one comparison group, but participants have not been randomly assigned to the two groups. Interrupted time-series design: a quasi-experiment in which participants are measured repeatedly on a dependent variable before, during, and after the interruption caused by some event. Matched groups: an experimental design technique in which participants who are similar on some measured variable are grouped into sets; the members of each matched set are then randomly assigned to different experimental conditions. Wait-list design: an experimental design in which all participants plan to receive treatment, but are assigned to do so at different times. Small-n design: a study in which researchers gather information on just a few cases.
