According to Leedy & Ormrod (2012), qualitative research incorporates looking at qualities or characteristics that are unlikely to be condensed to numerical values. Ideally, a qualitative research intends to survey multiple complexities and nuances of a specific phenomenon. Therefore, the qualitative research is mostly observed in research that involves complicated human circumstances or complicated human creations. On the other hand, quantitative research aims to establish the quantities or amounts of either one or multiple variables desired. The rationale of the study is to describe qualitative research, its key concepts, and the meaning of scientific merits.

The qualitative research was majorly used in the Experimental Methods in Political Science. However, the quantitative research was also incorporated in the study. According to McDermott (2002), most political scientists prefer quantitative analysis. The data was gathered in qualitative forms but coded in quantitative analysis appropriate for further related analysis. For example, the behavioral measures required an experiment to establish the behavior of subjects such as videotapes. The videotapes are later examined for characteristics including the facial expressions and dominance in the group. Besides, the physiological measures incorporate data such as blood pressure, galvanic skin responses, and the heart rate.

The Purposive Sampling in Qualitative Research Synthesis just like the title suggests, it is entirely a qualitative form of research. Suri (2011) reveals that an improved number of researches especially from the healthcare and education sector have recognized the benefit of using the qualitative research. Notably, the majority of the growing research appears to be dominated by quantitative research. The study on Ethical Principles and Guidelines for the Protection of Human Subjects of Research has used the quantitative techniques to scrutinize the research protocols (Human Research Protections, 2016). The essence of using the quantitative research is based on the availability to scrutinize the research protocols.

The key concept investigated in the Experimental Methods in Political Science is the review of the used experiments particularly in political science. Ideally, the first section provides a general synopsis of the experimental measures and designs alongside the threats to external and internal validity (McDermott, 2002). The study has also included the costs and benefits of using the experimentation. The study focuses on the experiments done in diverse fields such as political economy, individual choice literature, and behavioral economics. The study includes several forms of experimentation such as simulation studies, field experiments, and field studies.

The key concept in Purposeful Sampling in Qualitative Research Synthesis is the ability to make informed decisions concerning sampling that is essential in enhancing the quality of research synthesis (Suri, 2011). As a result, the research holds the sparse discussion on diverse strategies important for purposeful sampling as desirable in research synthesis. The key concept in Ethical Principles and Guidelines for the Protection of Human Subjects of Research is to establish some of the basic ethical principles that need to underlie the conduct of both behavioral and biomedical research that majorly involves the human subjects (Human Research Protections, 2016).

There are several ways through which the scientific methods could have been improved in the article. For example, the technique of analyzing the research merit should involve an evaluation of the abilities to coordinate the scientific activities (Estrela & Cury, 2013). Besides, training human resources and producing appropriate research is essential in enhancing scientific merit. Additionally, the research ought to ensure that it is tied to the unshakeable innovative and creative capacities and the ability to shift paradigms. The extent to which resources are invested in the study needs to be considered as a major indicator of improving the scientific merit of the research.
