Research is used to collect, analyze and interpret information systematically, to increase an understanding about a particular phenomenon (Sheperis, Young, & Daniels, 2010). Quantitative research uses statistical methods, instead of theory or logic, to test a hypothesis. In essence, quantitative research methods or designs, are used to observe and explain something that happens, used to collect and gather information, and analyze the information. Two types of quantitative research designs, used between groups, are the pretest-posttest control group design and within groups, the crossover design.
According to Sheperis, Young, & Daniels (2010) the experimental research design is an attempt to maintain control and or alter one variable effect on another. When used, the researcher is attempting to predict or determine what may occur, causal effect. The independent variable (IV) is the source of the manipulation. The variable being studied is the dependent variable (DV). In this way, the researcher is able to test, the hypothesis and reach a valid conclusion about the relationships between the IV and the DV variable (Sheperis, Young, & Daniels, 2010).
When using the experimental design research, the researcher, wants to make sure the population or group that is to be studied are similar. According to Sheperis, Young, & Daniels, (2010) “random assignment refers to the equal likelihood that a participant will be assigned to a treatment, control, or assignment…
