CPCE/NCE Research and Program Evaluation

quasi-experiment - Answer- uses preexisting groups, the IV cannot be altered and you cannot state with any degree of statistical confidence that IV caused the DV Experimental research - Answer- process of gathering data in order to make evaluative comparisons regarding different situations, it must have treatment controlled via the experimenter and random assignments internal validity - Answer- extent to which we can draw cause-and-effect inferences from a study. Was the DV truly influenced by the experimental IV? external validity - Answer- extent to which we can generalize findings to real-world settings Chi-square - Answer- statistical measure that tests whether a distribution differs significantly from an expected theoretical distribution Experiments emphasize parsimony, which means also known as Occam's Razor - Answer- Interpreting the results in the simplest way confounded experiment - Answer- occurs when an undesirable variable that is not controlled by the researcher is introduced in the experiment. Also known as a contaminating variable basic research - Answer- conducted to advance our understanding of theory applied research - Answer- also known as action research or experience-near research is conducted to advance our knowledge of how theories, skills and techniques can be used in terms of practical application IV - Answer- variable that the researchers manipulates, controls or alters. DV - Answer- expresses the outcome or the data. What we wish to measure the control group - Answer- does not receive the IV R.A. Fisher - Answer- pioneered hypothesis testing. hypothesis - Answer- is a statement which can be tested regarding the relationship of the IV and the DV in order to compare a control group to the experimental group the researcher will need - Answer- a test of significance descriptive statistics - Answer- describes data (mean, median and mode)
