Almost all quasi-experiments are somewhat creative or unusual in what they attribute the cause of something to, and this is the case because we aren't using a true experiment where we manipulate some independent variable in order to assess causality. Say, for example, during the course of your research a bunch of college students from Florida State on spring break descended upon your town and started partying wildly. Say, for example, a series of full moons came close together during the course of your study. The point is that neither of these would be the true trend, but they might be trends nonetheless. This allows identification of spurious and intervening variables, as well as a number of other variable relationship types like suppression effects .
Models also permit elaboration and specification .
Elaboration is the process of reclassifying or subclassifying your variables, sometimes even switching around your independent and dependent variables. For each of the following research studies, indicate whether the experimental procedures were carried out were correct or incorrect, and ethical or unethical. You must also tell me, in your own words, why you think so. 50 students in classes the instructor was teaching volunteered to participate in an experiment. The instructor then randomly assigned 25 of them to an experimental group and 25 of them to a control group.
