Document Summary

Used to make comparisons among diferent groups of individuals who cannot be randomly assigned to the groups. Variables are measured an not manipulated: correlaional instead of experimental but grouping and anova. Program evaluaion research: research designed to study programs with the goal of determining whether the programs are efecive. Single group design: uses a single group of paricipants measured ater they have had the experience of interest. 2360 students, slides are posted -> grades are measured once in the end. Single-group before-ater design: uses a longitudinal approach, has an advantage in terms of equivalence. No slides -> midterm grades -> posts slides -> inal grades: threats. Events change, changes in social climate, unrelated to manipulaion. Comparison group design: expected to be similar but not equivalent, random assignment not used. 2360*01, post slides -> inal grade, 2360*02, no slides -> inal grade: provides more informaion but . Diferences between the groups other than the intervenion.
