Document Summary
* situation is designed not a natural setting. * testing a small number of variables that the researcher controls. * want groups to be similar in all respects the theorized variable should be the point. Like sample selection probability of selection should be equal/mathematical. * random sample takes small number of cases from a larger population. * random assignment sorts cases into two or more groups. * can"t take account of all the variables. * dependent variable the outcome of the stimulus. * pre-test is the measurement before the stimulus. * post-test is the measurement after the stimulus. * we need an experimental group to receive the stimulus. * a control group does not receive the stimulus. * pre-experimental designs when compromises or shortcuts are types of design needed. * one-shot case study one group, a treatment and a posttest . * one-group one group, pretest, treatment and posttest.
