In this article, the author will outline the characteristics between qualitative and quantitative research, as well as their methodologies. The purpose of this article is to provide the reader with a brief overview of each research approach, determining the strengths and weaknesses of both. The terms “subjective” and “objective” will be viewed in accordance with each research paradigm by considering the role of the observer and addressing how the researcher conducts their analysis using these approaches. The author will also describe the preferred approach given to each modality and how each model can be used in an aggression study. Qualitative and quantitative are two differentiated research paradigms, which operate on the assumption that the results measured must be demonstrated to be valid and reliable. However, the distinctive element between each paradigm is the role of the researcher. Although they can be explained by the source of the data collected, qualitative data being a semantic text and quantitative data 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 & Lincoln, 2000). However, the quantitative approach identifies the role of the researcher as an external and objective observer, where the possibility of researcher bias is reduced and the final measured result is not subject to the researcher's interpretations (Patton, 1996). Two-dimensional method that uses an imperative and naturalistic approach. This design is associated with a phenomenological paradigm and is used by observing human behavior in... middle of paper... eliminates the need to participate in research by randomly mailing surveys. The qualitative methodology could use a focus group as an example. Where the researcher actively participates in asking open-ended questions, specifically to engage participants and suggest interpretive responses that reflect emotionality. When considering the manipulation of variables to alter observable and measurable conditions, quantitative analysis might include the manipulation of environmental factors, such as room temperature, lighting, etc., where the researcher is an external, independent observer. The qualitative paradigm would insist that the researcher participate in the manipulation factors using interruption techniques, verbal commands, etc., and would determine the measurable effects on the outcome through personal interpretation of the data.
