Quasi-Experimental Research vs. True Experiments

However using animals in studies to test hypotheses about human physiology would be incorrect; to find out about human physiology you would need to test humans.

In order to establish a more conclusive rate of effectiveness, the study would need to

A. A three year study done by Boston College found that “tests profoundly shape what

researcher are more certain that it was X that affected Y (Stanley, Boswell, et al, 2009).

Part B: How might each of the following concepts affect the results of the study?

Materials and methods describe the resources used in the experiment and how it was performed. Reading the methods of previous studies enables scientists to repeat the experiment and collect their own data. This data can be used to support other’s findings.

There was no hypothesis stated by the authors as to whether their research would or would not resemble NYHS’s study, however the authors probably did hypothesize that the same results would transpire over a longer period of time.

Concerning the cohesiveness of an essay, Pyrczak (2008) avers that its Results segment should not only convey a study’s outcome in paragraphs that can each convey a particular component of its findings but it should also be arranged in a manner that provides an exclusive focus on the research’s hypothesis as well as supply its related statistics. While this author can commend the researcher’s inclusion of the coefficients of their instrumentations and the tables that demonstrate the study’s results (Lin et al., 2004), the Results section in this composition falls short of the previously listed expectations of what this segment should comprise. For this assayer has observed that though the 10 variables measured had been noted, the study’s authors had not expounded upon the constituents of their findings. The rating this investigator gives the coherency of this paper is ‘2’.

The compiled data was used to form population A of the experiment, while population B was predetermined and provided by the instructor. Research was conducted using primary sources and data collected in order to locate evidence supporting the hypotheses.

Yes. The number of subjects were close, 30 vs 33. The SD of the experimental group was on 0.58% higher than the control group while the mean was only 1.84% higher. Neither of these differences is significant.

Researchers or research teams who elect a quantitative study are going to determine the relationship between an independent variable and a dependent variable within a population (Babbie, E.R., 2010). There are two types of quantitative study designs: descriptive and experimental. A descriptive design typically measures the subject once and establishes the association between the independent and dependent variables (Mujis, D, 2010). An experimental design measures the subject before and after a treatment and establishes causality between the variables (Brians, C.L. et al, 2011).

The results obtained in the three tests described above are consistent with the outcome of

Quasi-experimental research, which was once considered ‘flawed’ and less superior to true experimental research, has become increasingly popular over the last three to four decades in many areas, especially the social sciences (Coolican, 2014, p. 121). It differs from true experimental research design in the way that quasi-experimental research doesn’t involve random assignment of participants to groups and often has less control over the independent variable (Follmer Greenhoot, 2003, p. 94; Coolican, 2014, p. 121). An

All in all, the results displayed by the analysis of each study correspond to the overall effort of the posed research. For example, supported results aligned with study hypotheses, but signified that certain mechanisms underlie the criterion for each of the tested variables on different levels according to Ashkanasy, Falkus, and Callan (2000). Whereas, Beeri et al., (2013)
