t Tests and ANOVA in Clinical Practice
Summarize the study
The study that I chose is a single group quasi-experimental design that focused on answering the question that does nurses retain education and knowledge about evidence-based practices when they are assessed for the retention before receiving education, immediately after education, and then at the one-year mark (Cosme, Milner & Wonder, 2018). The sample population was a cohort of 62 students enrolled in their junior year of nursing school in the northeast at a single college. The data sources used were the Evidence-Based Practice Knowledge Assessment in Nursing (EKAN). Only 57 students participated int he full study. The inferential statistics were that the students would retain the education and knowledge at the one-year mark allowing for the school to set a benchmark. The actual findings did prove that the majority of students had growth and knowledge at the one-year reassessment mark (Cosme et al., 2018). The dependent variable was the compliance with education and assessment, and the independent variable was exposure to the additional education related to evidence-based practice knowledge meeting the definition as listed in the textbook (Gray, Grove, & Sutherland, 2017).

NURS 8200 Week 5 Discussion: t Tests and ANOVA in Clinical Practice
Inferential statistics enable researchers to apply the data they gather and the conclusions they draw from a particular sample to a larger population. As the name implies, inferential statistics focus on inferring whether there is a relationship between two or more variables. These statistical analyses include t tests and analysis of variance (ANOVA). t Tests are part of a group of statistical tests that test hypotheses; in fact, it is necessary to formulate a hypothesis in order to use a t test, because the results of the test can only be interpreted in the context of a scientific hypothesis.
Inferential statistics such as t tests work well for comparing two groups. Although mathematically equivalent to the t test, ANOVA allows for the comparison of more than two groups. Therefore, when three or more groups are involved, the ANOVA should be used.
In this week’s Discussion, you are asked to locate a current research article that utilizes either a ttest or ANOVA analysis. You provide a summary of the research study and of the study’s application to evidence-based practice. You also examine the article’s use of a t test or ANOVA and how either of those statistical analysis tools helped to inform the article’s conclusions and recommendations.

A Sample Answer for The Assignment: NURS 8200 Week 5 Discussion: t Tests and ANOVA in Clinical Practice
Title: NURS 8200 Week 5 Discussion: t Tests and ANOVA in Clinical Practice
Thank you, Natisha, for addressing the false impressions of fast weight loss with medications versus healthy lifestyle changes that bring slower weight loss but long-term effects. I have been very active most of my life. However, as years passed, it was more challenging to do active things because of the dictates of life. My weight increased substantially in the past six years, and exercise and dietary changes alone did not decrease my weight. With time, I would give up, try again later, and, with frustration, stop. This happened many times. In May, I hurt myself hiking in sandy mountains and was diagnosed with a broken back needing spinal fusion. I was instructed to lose weight safely but quickly for surgical success and longevity. Many of my friends were using semaglutide, and in desperation, I started it. I started walking daily (the only exercise I was allowed to do). I increased my protein, deleted my sugar intake (unless it was natural), and consumed food until I was not hungry instead of feeling full. These were all changes that had been attempted before, but now with success. I lost 40 lbs in four months in preparation for the spinal fusion and then an additional 10 lbs in an additional four months post-surgery as my exercise routine was being rebuilt. The semaglutide lowered my cravings, allowing me more power to make better, consistent choices, resulting in positive effects. My experience aligns with the effectiveness of semaglutide in reducing body weight, as your research has highlighted.
I have known diverse individuals who have admitted using semaglutide as a weight loss program. Many have yet to succeed. Those who have admitted no success also stated they did not make lifestyle changes. Kebbe et al. (2020) affirmed that the extent of healthy lifestyle behavior changes that are embraced and cultivated will prescribe the success of weight loss. This emphasizes your research recommendations for the combined medication and behavioral change approach. This underscores the importance of a holistic path to weight loss and improved health. Those I know who have succeeded with this combination approach have had varied durations to reach their weight loss goal. So, the perception of guaranteed quick weight loss is unrealistic as we are each individuals with unique physiological functions. Thus, in prescribing this medication, healthcare providers are responsible for constructing realistic expectations for patients.
Additionally, patients should be educated on potential side effects to comprehensively understand that substances that provide a positive effect also have the potential for undesirable responses. Currently, data supports possible adverse events of hypoglycemia, gastrointestinal side effects, pancreatic safety, thyroid cancer, gallbladder events, cardiovascular aspects, acute kidney injury, and diabetic retinopathy (Smits & Raalte, 2021). However, current research also supports the overall beneficial risk/benefit profile. Thank you for your research.
