All science advances through the rigorous application of the scientific method. Part of this process involves the development of an empirical research design that can help researchers determine whether or not the hypothesis being tested is likely to be true. Good research design is based on a researcher's empirical observations and a review of the scientific literature. The information garnered from these sources is then formulated into a testable hypothesis that can be analyzed using inferential statistics. The research design used to test this hypothesis needs to not only consider the effect of various levels of the independent variables on the dependent variables, but also control as much as possible any extraneous variables that are not related to the research question but which might affect the results. The experimental data are analyzed to determine their statistical significance and the likelihood the null hypothesis is true using statistical tests.
