hypothesis

The first method that is commonly used for evaluating evidence is meta analysis. Many studies with the same rules used from study to study will yield the results that are then summarized (Study.com, 2018). Advantages include a better estimate of the relation that exists in the population than single studies, the estimates are more precise because there is an increased amount of data and statistical power, hypothesis testing and biases associated with publications can be examined, and it helps resolve inconsistencies in research, and identifies potential moderating or mediating variables (Stone & Rosopa, 2017). A major disadvantage is inadequate sample size. On the other hand, another study that is used is systemic review. For example, A systematic review is a form of analysis that medical researchers carry out to synthesize all the available evidence on a particular question, such as how effective a drug is (Medical News Today, 2016). This type of review is beneficial in that the study is the same and follows the same guidelines. By using this method which is reliable it can help to identify the best benefits of a new drug and how implementing it would be successful.

Systematic review- provides answers to research questions that are well defined by the collection and summerization of all data collected that fits into the required criteria. Systematic reviews help in identifying, assessing and summarizing the findings of all individual studies relevant to the medical issue being evaluated. This type of evaluation requires the reviewing of related liturature including the results of carefully designed and closely monitored controlled trials. These random controlled trials are considered to be the gold standard for a clinical trial. Valuable in determining the efficiacy and effectiveness of medical interventions.
