Advantages of Explanatory Research Design Marketers don’t have any machines to look inside a decision problem, so they may use certain research processes to “open up” the problem and look around. These study designs all have similar components (as we’d expect from the PICO): A defined population (P) from which groups of subjects are studied. The experimental and quasi-experimental designs, along with their strengths and drawbacks, are discussed in this chapter. data. Figure 6.2 shows how experimental, quasi-experimental, and non-experimental (correlational) research vary in terms of internal validity. True experimental design is regarded as the most accurate form of experimental research, in that it tries to prove or disprove a hypothesis mathematically, with statistical analysis. Experimental research design is centrally concerned with constructing research that is high in causal (internal) validity. Statistical tests can be used to show statistically significant differences between groups in a survey. ): Cohort studies more clearly indicate the temporal sequence between exposure and outcome, because in a cohort study, subjects are known to be disease-free at the beginning of the observation period when their exposure status is established.
