We are encouraged to use either the qualitative or quantitative research methods when undertaking a research program in any field. In the nursing and medical field a research work enables us to rigorously investigate a certain situation and generate or validate the new or the existing knowledge in the field. In most cases research work in health care and nursing field takes place to investigate the health care, economics, environmental issues, vitality, treatment and development theories that revolve around health care and nursing field. This paper will seek to analyze some important rubrics which are vital in compiling either a qualitative or a quantitative research papers.

In my initial rubric, I will try to compare and contrast the quasi-experimental and the experimental research designs. Mostly, the experimental design employs some random assignment of units and subjects in a certain condition in order to generate a hypothetical conclusion on it. This is where the research uses the nursing students, patients and health care institutions as the random assignments in their research work (Burns & Groves, 2007). The quasi-experimental design on the other hand does not assign any random units; rather they compare groups and units which are already in existence. At times they use covariance analysis to determine the statistical control for the pre-existing health care unit (Minichiello et al, 2004).

It is important to understand that the two attempts to create a design scheme which gives the most appropriate results to the question at hand. Quasi-experimental and the experimental designs tend to have a similar data collection and analysis perspective. But in some cases quasi-experimental design uses the statistical techniques such as the t-test, correlation, regression and factor analysis in generating their results (Tesch, 1990).

Correlational research is the methodical investigation of the relationship between two variables. The purpose of the correlational research is to evaluate the association between the two given variables. In this case the research uses the already existing events to determine their relation with one another. Correlation enables the researcher to make some predictions based on the past experiences of variables and units.

The prospective research approaches mainly set goals and aim at defining the dependent and influencing variables in the research. In addition, prospective research analyzes how the dependent variables change with time. This approach is mainly suitable if you are researching on medicine or health care related fields. Retrospective research analysis on the other hand is based on observation and examination of past events. Such research work is wholly based on the existing database. It is suitable for history, financial and economics dissertations (Benard, 1996).

Rigor is the in-depth investigation of the sample units in a research. In most cases rigor determines the reliability of the research as it assures its validity and trustworthiness to the results. The rigor norms are mainly applicable in qualitative research which is mostly aligned to nursing since the concepts, measures and procedures have to attain some trustworthiness in them (Burns & Groves, 2007).

Phenomenology is a study which seeks to analyze research in the first person point of view. It can also be defined as a theoretical orientation which barely generates deductions which can be empirically tested.

Grounded theory is a systematic methodology which seeks to generate theories from some data. It is mainly used in both qualitative and quantitative analysis. Grounded theory is mainly a case guided research and it assumes that there is an interaction of variables throughout the paper. It uses some simple additive models such as ANOVA to analyze those variables (Ryan & Bernard, 2000).

Ethnography is the study of systematic recording human cultures and behaviors. It is used to analyze the descriptive practices of people in a given research work. It also involves an in-depth description of everyday life and practice.
