Between (cid:862)i(cid:374)depe(cid:374)de(cid:374)t-g(cid:396)oups desig(cid:374)(cid:863) each participant is randomly assigned to only one condition (i. e. , level) of the independent variable: post-test only, pretest/posttest. Within-subjects designs (cid:862)(cid:449)ithi(cid:374) g(cid:396)oups(cid:863) each participant is presented with all conditions (i. e. ,) levels of the independent variable: concurrent measures, repeated measures. Iv conformity pressure (2 levels conformity and control) Independent variable with two or more levels: participants are randomly assigned to a particular level of the iv, participants are tested on the dv before and after the instantiation of the iv. Hypothesis framing a task as being diagnostic of work ethic might lead to difference in performance, compared to an intelligence framing.
