In this article, the author will delineate the characteristics between qualitative and quantitative research, as well as their methodologies. The purpose of this article is to give the reader a brief overview of each research approach, determining the strengths and weaknesses of both. The terms “subjective” and “objective” will be understood according to each research paradigm by considering the role of the observer and addressing the way in which the researcher conducts his analysis using these approaches. The author will also describe the preferred approach given to each modality and how each model can be used in a study of aggression. Qualitative and quantitative are two differentiated research paradigms, which start from the assumption that the results measured must be proven valid and reliable. . However, the distinguishing element between each paradigm lies in the role of the researcher. Although they can be explained by the source of the data collected, the qualitative being semantic text and the quantitative being in numerical form, in the qualitative paradigm the role of the researcher is to be an active participant within the study , conferring the subjectivity of the interpretation. to the final measured outcome (Denzien and Lincoln, 2000). However, the quantitative approach views the researcher as an outside, objective observer, where the possibility of researcher bias is reduced and the final outcome measured is not subject to the researcher's interpretations (Patton, 1996).Qualitative ResearchQualitative Research is a multiple approach. -dimensional method which uses an imperative and naturalistic approach. This design is associated with a phenomenological paradigm and is used by observing human behavior in the middle of an article......to eliminate the need for research participation by sending random mail surveys. Qualitative methodology could use a focus group as an example. When the researcher actively participates by asking open-ended questions, specifically to engage participants and elicit interpretive responses reflecting emotionality. When considering the manipulation of variables to change observable and measurable conditions, quantitative analysis could include the manipulation of environmental factors. factors, such as ambient temperature, lighting, etc., for which the researcher is an external and independent observer. The qualitative paradigm would emphasize that the researcher participates in manipulating factors by using interruption techniques, verbal commands, etc., and determines measurable effects on the outcome through personal interpretation of the data..
