U6: Establishing audiences Quantitative: Quantitative research is a form of research where people are asked something with a simple answer that can be quantified afterwards to represent a larger group. This type of research has simpler answers (yes or no) than qualitative which has more complicated answer (such as a paragraph of text) that can not be quantified but tells a lot more information with 1 answer. Quantitative research is quicker and easier to gather result. Quantitative research can be used for things such as seeing how much of the population in the UK like corn flakes. They would do this by making a survey with a simple answers for the person being surveyed to choose from, the people doing the survey would be people chosen at random
Base on the type of service that was provided to the patient and the concept of the establishment of the healthcare practice guidelines, the evidence-based practice that was identified was the level I which is the evidence of randomized controlled trials (RCT). The level I RCTs, which is the meta-analysis level and sometime called the hierarchy of evidence of all relevant, are assigned to studies based on the methodological quality of their design, validity, and applicability to patient care which According to the Medical News Today (2014) stated that the randomized controlled trials in the use of clinical intervention and the procedures are the gold standard of scientific testing and in a research study. The purpose of the RCT it is to support
1. What rationale do the author(s) give for conducting the study? The author that is conducting this research is testing the obedience of a subject when dealing with “stocking a victim” by use of a shock generator. There are thirty levels of shock that are generated varying from a slight shock to a severe shock.
The use of quasi-experimental research design is appropriate when the study has control and manipulation of the independent variable, but lacking randomization (Loiselle, 2011), which was restricted by institutional policies (Koskinen et al., 2016). The non-equivalent control group pre-and posttest design is the most frequently used quasi-experimental approach, which allows determining pretest similarities
The appraising process was the most difficult from this activity but was one of the most important steps in selecting our evidence. Questions in the table such as “Is the aim of the study clear?” , “Were the subjects randomized?” and “Was there a control condition?” etc provided an objective method to evaluate the articles and their research.
The design of a program must be strong and evidence-based as well if researchers want their study to be perceived as
Methods of research circulating a quantitative approach will not have results of qualitative data that will affect the conclusion, this also eliminates the potential of risk of biased conclusions as the results gained from the experiment merely statistical and cannot be influenced in any way. According to Deborah D. Cupal’s experiment (2001) “A treatment consisting primarily of relaxation and guided imagery produced significantly greater knee strength and significantly lower levels of reinjury anxiety and pain to placebo and control conditions.” The use of method used in the experiment highlighted that the method was the best to use in the research, as the results were numerical which could be used in the conclusion of the experiment. However, if there are any outside factors that affects the athlete’s ability to perform the tests in the correct manner, then lies the potential risk of the results becoming inaccurate creating anomalies in the results. Because of this results may not be as correct as the researcher wanted to get, this could cause the overall conclusion to become incorrect and negatively affect the reputation of that researcher especially if it has been published when
Discuss the methodological and ethical issues which are apparent in this study. How have the findings impacted the psychological field? One methodological issue with the Bain et al refrigerator study is that type of experiment used. Having used a laboratory experiment, all variables were under strict control and this does not reflect the true nature of the situation the children were placed in. Children trapped inside a refrigerator would not escape by pressing a panel on the floor, thus the experiment has features which do not reflect an accurate representation of a real life situation (Bain et al, 1958).
After reading the article I discovered that the results from my experiment were highly correlated to the experiments that were conducted in the article by authors Brennan Davis and Collin R. Payne.
Examples of such research are clinical trials, experiments conducted in the laboratory, and controlled random trials. The second component is clinical expertise, the observation and exposure gained over time. An example of clinical expertise is inductive reasoning. The third and final component of evidence-based practice is patient benefits. This is the “unique preferences, concerns, expectations, financial resources, and social supports” each patient brings to the clinical consultation (Greiner & Knebel, 2003, p. 57).

According to Creswell (2014), this would make the research approach, mixed method. Mixed method research is the combination of qualitative and quantitative research (Creswell, 2014). The researches used interviews, which would be considered qualitative. In addition, scales and indexes were used which do not allow for any explanation from participants, and would therefore be considered quantitative (Creswell,
a. What is the primary question posed by the study? What hypothesis or hypotheses are investigated? • How do relationships effect men and women’s self-esteem and ego differently? The hypothesis for Study 1 was that women rely on relationships for self-confidence more than men, but on paper men will report relying heavier on relationships than women. The hypothesis for Study 2 was that men will score higher on the RELCSW scale opposed to women.
In quantitative research, variables are identified and defined, and then relevant data is collected from study participants. A strength of this type of research is that the data is in numeric form, making it easier to interpret. It also studies the relationship between independent and dependent variables and can address questions such as does a relationship between variables exist, what is the direction of the relationship, how strong is the relationship between the variables, and what is the nature of the relationship. To be able to discover and answer the cause-and-effect relationship is a strength of quantitative research. Lastly, in quantitative research, the study can either be experimental or nonexperimental, meaning clinical trial or observational study, allowing for different types of research studies to be conducted.
