Quantitative VS Qualitative Research – Coursework Example

RESEARCH RESEARCH Forensic behavioral science can be defined in its simplest and most basic terms as any of the scientific disciplines including psychology, sociology, and anthropology that involve the collection of physical evidence and its subsequent analysis by observing the actions of human beings. It mostly focusses on addressing criminal issues through detecting the assailants and victims of crime. Criminal activities may range from terror activities to domestic violence in the family.
When conducting forensic investigations the researcher might resort to qualitative approach because it is systematic and rigorous in defining the problem or developing an approach to the problem. It also offers a deep insight into the issue at hand. It employs the following method of data collection during inquiries; in-depth interviews where you get to talk physically to the participant and get their opinion or testimonies. Other methods include uninterrupted observation, participant observation, ethnographic observation, and review of documents. It therefore, helps the researcher to understand processes and especially those that emerge with time provide adequate information about the context and the setting (Berg & Lune, 2004). An example of a case that would prompt the use of qualitative approach is trying to find out the causes of increasing crime rates in and other vices like rape in the city.
The use of quantitative on the other hand might be considered when relationships among variables are to be established. It could also be used to test a particular hypotheses or theory related to crime. The methods of data collection in this approach include the use of surveys and audits. This approach has the ability of establishing the cause and effect of a crime. For example the rate of crime in the city could be measured and its causes and effects discussed. For example it may turn out that the rate of crime is higher due to the high number of unemployed youths in the cities. Therefore, qualitative is preferred when the researcher is after understanding a concept while quantitative is sought whenever comparisons are to be made or when the researcher wants to establish the cause and effects of crime in a city this will be the best approach to go for.
Mixed methods involve the use quantitative and qualitative together. This is always opted for when the researcher wants to understand a concept and at the same time quantify it (Patton, 2005). For example the researcher may want to know the leading cause of crime in the city and at the same time want to establish the prevalence of crime in the city or put it in a geographical context and how it is spread in the city.
