Document Summary
You are studying your idea of conformity may be interpreted differently to others. Welsh 2: measuring experimental context context e. g. surveying kids at the boys & girls club. Types of evaluation research designs: experimental designs, quasi-experimental designs: non-rigorous inquiries somewhat resembling controlled experiments but lacking key elements such as pre- and post-testing and/or control groups. E. g. childre(cid:374)"s (cid:373)e(cid:373)or(cid:455) e(cid:454)peri(cid:373)e(cid:374)t he spoke about, (cid:374)o pretest o(cid:374) a group of only seven children usually used in marketing to generate results fast. Two observations of class participation: before and after an open discussion example of. Quasi-experiment: the trend existed prior to the controversial discussion, therefore, it does not prove anything. If it went 4-> 4 then ->8 maybe the results would mean something. Basing conclusions on two observations alone is not sufficient research. Happens usually due to convenience or cost restrictions. Not usually representative of the population, more representative of one another: we want randomization to eliminate researcher bias.
