Document Summary
Psyc 2001 between- and within-subjects design: part 2. Likely the most widely used experimental design due to their pros , i. e. , advantages they present to the experimenter. Consider following experiment: group 1: tr(pass) then tr(tutor, group 2: tr(tutor) then tr(pass, both conditions: test for learning (midterm and final exam) In this case, we assume that pass techniques will influence performance (& learning) during tutor phase (grp. 1), & that the tutor phase will influence performance in pass phase (grp. 2: in both cases, we assume that there"s a carryover effect and that it ends up being the same size. We expect that 1 might be more effective (e. g. , tutoring > pass), e. g. : grp 1: pass (80%) & tutor (90%, grp 2: tutor (90%) & pass (90%) Design-type effect (e. g. , erlebacher, 1977): magnitude, or existence, of an effect is dependent upon experimental design used. Many experiments have demonstrated that design-type interacts w/ independent variable to assess it that"s being manipulated.
