The Potential Real World Impact Of Research

When conducting research data is gathered from a sample. The data can prove or disprove the hypothesis. When reviewing the data, a person can become bias and only use the data that they feel is beneficial to their study. Rubin and Babbie (2014) write about the two types of sampling bias: Conscious and Unconscious. The authors state “When we speak of bias in connection with sampling, this simply means those selected are not typical or representative of the larger populations from which they have been chosen” (Rubin & Babbie, 2014).

The researchers used purposive sample but did not give any explanation as to why this choice sampling was made. It is essential to describe the sampling process in a research where this facilitates the reader to distinguish any bias in the whole sampling process. In studies using participants, the process of how to select, access, inform and retain research participants requires considerable thought. Sampling is a key issue, because it is

In reviewing this article, this writer was able critique the study and the suitability that it can possess if applied to actual practice. An important factor on whether a study can be considered valuable is if it is transferable in other situation, that is, a study's results should also be reflective if duplicated on other samples (Polit & Beck, 2006). Thus, the statistical power, internal and external validity are important to observe and note (Polit & Beck). If this writer were to carry out this study, it would have to be reflective of how the researcher performed it originality.

External validity is when research findings are applied to the real world. When looking at 19-21 year olds on a college campus, we need to study a broad range of individuals coming from different cultures and backgrounds. We also need to look at which situations these are being applied to such as where they are there drinking habits taking place.

A research critique aims to measure the value and significance of a study. These are determined by

The article’s researchers believed that it is necessary to research the efficacy of these claimed evidence based interventions.

While the methodology of the research seemed solid, there were factors which were out of the control of the researchers which made the process more difficult to verify. Because the researchers chose a public web forum, they were unable to verify the legitimacy

In order to know whether the evidence of research studies are accurate, one must be able to have a fundamental understanding in statistical analyses to determine if such descriptions and findings within manuscripts and articles are presented correctly and explicitly (Sullivan, 2012). Proper use of statistics begins with the understanding of both descriptive and inferential statistics. Correct organization and description of data characteristics from the population sample being studied leads the researcher to identify a hypothesis and formulate inferences about such characteristics. It is with inferential statistics that researchers conduct appropriate tests of significance and determine whether to accept or reject the identified null

Researchers tend to draw conclusions and/or generalizations from the sample of participants in order, to generalize about others that are not in the specific study (Trochim & Donnelly, 2008). Therefore, it is essential that researchers learn

studies (such as Bifulco, Cobb & Bell, 2009). As a result, the present study fills a

Prior to this course I thought I could look at current research and appraise a study; however, after this course I determined my knowledge about research studies was limited. Now when I look at the sampling methods and how the data was analyzed I can review it with a new lens. This is especially evident with how samples are determined. Establishing how a sample will be taken is of utmost importance and according to Polit and Beck (2017) validity of a study is directly impacted by how the sample is obtained and how it can be generalized to the overall population. Many factors can cause a sample to not be representative or result in bias through convenience sampling. When I look at a study now I look at

External validity refers to the degree to which the results of a study can be generalized to other individuals, setting, and times.

Testing the effect of every possible combination of evidence-based interventions and every possible factor that might be related to outcomes is logistically unfeasible. Therefore, a research program informed by theory-driven hypotheses is crucial for facilitating a rational use of research resources in these areas (Vivanti, 2017, p.114-115).

In the modern age of health,education and public safety, society relies on rigorous research methods to find answers to complex issues dealing with social issues and general concerns. Ultimately, some short-term research methods may initially fail; however, continued extended research should surely result in success and benefit future generations. Depending on the topic of research; some research methods might be more appropriate than others. For example, clinical and laboratory experimental trials might receive better consummation if they use Quasi-experimental and Classical Experimental design rather than Cross Sectional Studies and Longitudinal Studies which focuses more on psychological experiments and behavior studies (Addison) (2015).

Psychological research may be undertaken on a subset of society; however the importance of the results may have an effect way beyond the group tested. The value of psychological research varies and the same results can be used in different ways by different groups of society.
