Research and Criminal Justice

According to Yin (2003), there are two types of research approach. This includes quantitative research approach and qualitative research approach. A quantitative research emphasizes on transforming the data to numbers, quantities and statistics to formulate facts and to uncover patterns in a research. It addresses research purposes through empirical analysis that involve numerical measurement, the relationship between variables and analysis approaches (Zikmund et al., 2010). The sample size being investigated is typically large (Anderson, 2006). Quantitative research mainly uses questionnaires, surveys and other equipment to collect numerical or measurable data (Anderson, 2006). On the other hand, a qualitative research typically emphasizes words more than numbers

This paper primarily concerns qualitative research, but we were asked to compare both qualitative and quantitative methods. During comparison, there are many noted differences in both study designs, but not many similarities. Qualitative research uses a subjective approach with a large sample population. It collects non-statistical data, using an unstructured or semi-structured technique (Nieswiadomy & Bailey, 2018). Quantitative research uses an objective approach and large, random, sampling to ask opinions in a structured way. The findings of quantitative studies are conclusive and used to recommend a final course of action (Nieswiadomy & Bailey, 2018). While it is hard to see similarities between the two, both methods aim to find a solution to a problem or question, the researcher doing the study may affect the outcome and an analysis of the collected data must be done (Souza, 2017). What many don’t realize is the connection amongst the two. You can say, both types of research build upon one another, meaning quantitative studies can quantify results found in qualitative research (Souza, 2017).

The role of this psychology field is to evaluate laws that is brought up to their attention to add too, revise or remove all together. According to Garrison (N.D), research for Criminal Justice policies is to reduce crime by analyzing and assessment. This psychology role is essential to law enforcements because it can affect the laws that we follow in either a positive or negative way. An example of a policy evaluator at work would be to conduct research on the policy of teenagers being able to dropout of school at the age of sixteen. A question that might be asked pertaining this law would be “Will it increase graduation numbers?” This career field can affect a community so this task can’t be taken

Qualitative research is subjective data and is often used in the social sciences (Sarantakos 2013, p. 48). Qualitative research is devoted to gathering facts, this can be completed through personal experiences, behaviours, and observations (Sarantakos 2013, p. 46). The purpose of qualitative research is to gather an in depth understanding of human behaviour and the explanations for the behaviour (Martijn & Sharpe 2006, p. 1). An issue with only using a qualitative method is efficacy, qualitative studies cannot address relationships between variables with the degree of accuracy that is required to establish social trends (Sarantakos 2013, p. 46).

Once the researcher knows what information to collect and where to find it, the first step in the data collection process is to organize the data on a constructed collection data form. This process allows the researcher to make

Methods used in psychological research are used to obtain quantitative or qualitative data. Quantitative data is more often than not derived from methods such as experiments and statistics analysing data using surveys, questionnaires and interviews. Qualitative data tends not to be aimed at finding exact measurements in its findings, but is more concerned with evidence collection and analysis through practices such as observation and ethnography (using observations through involvement in activities over a period of time) (Brownlow 2011).

Quantitative and qualitative research generates from two different perspectives, and it provide different types of crucial information from the research subject. Qualitative research corresponds more with comprehensive and thorough descriptions of events, whereas quantitative research creates statistical models to explain events. Several advantages and disadvantages in qualitative and quantitative research, depends upon the researcher's purpose and area of focus and information that will answer those research questions (Creswell, (2013).

The researcher must set a clear hypothesis, showing the relationship between independent and dependent variables. In quantitative research tools are used to collect numerical data. The information can be gathered using questionnaires or some type of equipment. Quantitative data is efficient at testing a hypothesis, but can miss contextual detail. In quantitative research, the researcher is often objectively separated from the subject matter. One of the ways quantitative research is different from qualitative research is that quantitative research requires extraction of large amounts of statistical data. Qualitative research is focused in on personal viewpoints and opinions of a smaller number of subjects (typically). Qualitative research can take more time than quantitative research (McCusker & Gunaydin,

Data collection methods- the researcher needs to pick how the information for this subject can be collected (observation, questionnaires, interviews) and so forth. Analysis and presentation of findings- the researcher needs to use reports and other information gathering it into one to present the hypothesis. Conclusion- what does the studies say about this topic, this is based on all the information that was gathered together to get the correct conclusion.

In criminal justice research is the basis for maintaining an effective system. It helps to discern what methods of correction or deterrence are most impactful, what mannerisms, behaviors, and events drive criminality, and what crimes are most prominent in our society among a slew of other things (Maxfield, Babbie, 2015). Research is detrimental to the propulsion of our society as a whole, and within our criminal justice system, it can be the difference between the procurement of a functioning society and anomie.

Criminal justice field is growing every day. It grows with the help of technology and society. When the technology evolves and society grows the criminal justice has to evolve and grow to fit the society needs. Whether it is an easy or hard change the criminal justice system never fails us. With any state the criminal justice system is to protect and serve the community so the more it evolves the more the system has to. The following paper discusses the past and future trends that connect the societies and the criminal justice system. This paper also discusses how the influential the trends effect the surroundings society. It also talks about the recent and future

Information-Gathering TechniquesA. InterviewsTo begin my research, I would take the interview approach. In order to conduct a successful interview I have create some interview criteria.

There are a number of methods of collecting data, some of them are – questionnaire, surveys, checklists, interviews, observations, focus group etc (Cordray, 1986; Einhorn and Hogarth, 1986).

Academics can be used in two different ways here; learning to help criminal justice professionals and providing information for students. Just like our textbook, criminal justice research can be done for academic purposes to teach all aspects of Criminal Justice. Criminal Justice classes range from high school to graduate school, that means there needs to be academic resources for all those years’ worth of learning and teaching. But it can also be to learn more about the Criminal Justice system as a whole for those who are working in it. For example, research may be done to learn why adolescences are behaving the way they are. Then social service personnel can read and learn from this research to further help
