Quantitative Research Design
The research design of this study is clearly presented in the beginning of the article within the title. This quantitative study used 2 x 2 mixed model design to conduct their study, which included an experimental group and a control group (Sullivan-Mann et al, 2009). This method was appropriate because it compared each groups results to see if the results vary therefore testing the hypothesis and answering the research question. The experimental design used was the pre-test/post-test, which was the most appropriate design used because it compared the experimental and control group to evaluate if the critical thinking scores varied among the groups. The ways in which this experimental design protected internal validity was by utilizing randomization, which prevented selection bias, limiting the amount of time to conduct the study, which reduced the incidence of mortality and applying the pre-test/post-test evaluation to protect against all threats to internal validity (Sullivan-Mann et al, 2009). One disadvantage to this quantitative study is its threat to external validity. The threat that is a concern is the reactive affect to the pre-test. By giving a pre-test, the subjects are being sensitized to the material being tested, which can affect the validity of their post test scores. This research design allows the researcher to conclude an independent and dependent relationship between the variables. The independent variable being simulation scenario and the dependent variable being critical thinking. In this experimental design, the researcher chose not to control the extraneous variables, which resulted in a number of limitations.

...rse (Sullivan-Mann et al, 2009). At the end of the study, students were given the post test to determine if critical thinking was enhanced. The reliability was not specifically stated, however knowing it was a true experimental study, it can be inferred that reliability was obtained. A threat to external validity was inferred, but not clearly stated being the reactive effects of the pre-test. The study also had threats to internal validity, which was not clearly stated. The researcher stated that the sample group was small, but did not state how this effected validity. However, based on our knowledge of research we can infer that mortality was a threat to this study. Due to the small group and the two students that dropped out of the study after taking the pre-test, the results in the end could have been skewed based upon their results (Sullivan-Mann et al, 2009).

Discussion Board Selecting A Quantitative Study Design Essays

- Discussion Board Selecting a Quantitative Study Design After reading the Creswell chapters, and the supplemental texts I was able to develop a research topic that could be explored through multiple research designs. Originally, I proposed the use of a correlation study in order to identify the “direction and degree of association” between retention rates of first year teachers and job satisfaction (Creswell, 2012, P. 354). I clearly outlined my independent and dependent variables, collection process, and study limitations....   [tags: Scientific method, Research]

Combined Qualitative and Quantitative Study that Employs two Phases Sequentially

- The essential focus of this two-phase sequential mixed methods study is to determine if a relationship exists between a generation category (Gen X, Gen Y, Gen Z, etc.) and the number of incidences of bullying in secondary education. The study was proposed as a result of a significant increase of bullying in the news, more importantly, due to the recent suicides that resulted directly from bullying. In the first phase, quantitative research questions will focus on the statistical analysis between each generation category and the number of incidences of bullying during their secondary education....   [tags: research design, qualitative interviews, bullying]

Essay on Quantitative Methodology For Quantitative Research

- Quantitative research involves the collection and converting of data into numerical form to enable statistical calculations be made and conclusions drawn. It provides a measure of how people think, feel or behave and uses the statistical analysis to determine the results. However, this measurement results in numbers, or data, being collected, which is then analyzed by using quantitative research methods (Byrne, 2007). There are hypotheses or questions that the researcher wants to address which includes predictions about the possible relationship between two they are investigating (variables)....   [tags: Scientific method, Quantitative research]

Essay on Correlation Between Quantitative And Quantitative Research

- When it comes to research, there are two approaches that are effective in gathering reliable information, which is qualitative and quantitative research. It is important to be able to distinguish between the two, as they are very different and can often become confused as the other. Quantitative research is a type of research that uses numbers and measures gathered from a large sample population (Berg & Lune, 2012, p.3). In order to receive data, it uses paper surveys, online questionnaires, online polls, and telephone interviews as these methods can produce numerical results (Berg & Lune, 2012, p.3)....   [tags: Qualitative research, Quantitative research]

Using Qualitative And Quantitative Methods For The Research Design Essay

- There is a variety of research designs available for researchers to choose. However, it is essential that researchers choose the most appropriate research design for their study. Consequently, the research design is chosen from three categories of methods that include quantitative, qualitative, and mixed (Creswell, 2014). The purpose of this paper is to formulate two hypothetical research designs using qualitative and quantitative methods for the intended research topic. Quantitative Method: Survey Research Design The first hypothetical research design selected is survey research....   [tags: Scientific method, Qualitative research]

Essay about A Research Study On Quantitative Research

- Many describe Quantitative research method as the oldest form of social research and trusted by most researchers as they believe that anything that has been proven with the help of numbers cannot be wrong (Alston & Bowles, 2012, p. 10). Basically Quantitative method deals with numbers, the researcher 's own presence is minimal and has deductive approach. It is most commonly used when, one began with a Hypothesis and that needed to confirm or reconfirm through research. It is a type of research in which the researcher decide what to study, ask specific questions, collects quantifiable data, analysis these data and conducts the enquiry in an objective manner....   [tags: Scientific method, Qualitative research]

Qualitative and Quantitative Research Essay

- Qualitative and Quantitative study designs both can be beneficial in research design. They both provide valuable options for researchers in the field. These techniques can either be used separately in a research study or they can be combined to achieve maximum information. This paper will define the terms qualitative and quantitative; describe the similarities and differences between each; discuss how qualitative and/or quantitative research designs or techniques could be used in the evaluation of my proposed research; and discuss why linking analysis to study design is important....   [tags: Research Methods]

The Nature of Quantitative Research Essay

- The Nature of Quantitative Research Quantitative Research Defined: According to Huysamen (1997), "descriptions of quantitative research typically discern a cycle of successive phases of hypothesis formulation, data collection, analysis and interpretation." Using a deductive approach, quantitative research seeks to establish facts, make predictions, and test hypotheses that have already been stated. A large part of the data analysis of quantitative research is statistical, striving to show that the world can be looked at in terms of one reality; this reality, when isolated in context, can be measured and understood, a perspective known as positivism (Gay & Airasian, 1999)....   [tags: Quantitative Research Papers]
