Experiment Research

McGlone and his colleagues used a 2x2 factorial design. Explain why this design was necessitated by the research hypotheses.

Various advancements in the fields of study have resulted in development of specific methods and models for research, which do not only assist in finding solution to the problem but also help the researcher in carrying out the research properly. The researches that make use of two different variables, with each of them having two different levels, 2x2 fractional designs are generally employed and same is the case with the research under discussion. McGlone and his colleagues presented the hypothesis that assigning agency to the virus generally results in heightening of perceived severity as well as personal susceptibility in relation to the human agency assignment. Thus, the two major variables used in the research are: agency assignment language and the virus image.

It should be taken into account that the researchers have made use of two different levels of two independent variables, which makes 2x2 fractional design suitable for use in the research. On one hand, the design has assisted the researchers in making the right comparisons in appropriate manner and at the same time, the same has also allowed the researcher to form a link between two independent variables at the same time.

Experimental control is a critical feature of any experiment. If we wish to know the effects of independent variables on dependent variables we must "hold constant" other variables that would make causal inference challenging. What efforts were taken in this experiment to achieve high level of experimental control?

In this experiment, the researchers have made sure that the severity and susceptibility of getting disease did not overweight reliance on control system. The control did not only play an effective part in producing effective results but at the same time these allowed the sample in overcoming the fear factor. In order to make sure that the experiment is carried out in the right manner and the variables are rightly dealt with, it is essential to exhibit proper control on the variables. There are certain variables in every case that are expected to exert influence on the final results and thus it is essential to make sure that they are properly controlled and rightly managed. It is eminent to mention here that inability to control these variables might cause interference with the results and thus cause might even lead the researcher ...
