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 t
test 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.
To prepare:
Consider some of the important issues in health care delivery or nursing practice today. Bring to mind the topics to which you have been exposed through previous courses in your program of study, as well as any news items that have caught your attention recently. Select one topic to consider for this Discussion.
Next, review journal, newspaper, and Internet articles that provide credible information on your topic (you can choose any nursing topic from Confidentiality or Work Place Bullying or any other nursing related issue that will be easy to locate a scholarly research article on which uses a t test or ANOVA)
Then, select one research article on which to focus that used inferential statistical analysis (either a t test or ANOVA) to study the topic.
With information from the Learning Resources in mind, evaluate the purpose and value of the research study discussed in your selected article and consider the following questions:
Who comprised the sample in this study?
What were the sources of data?
What inferential statistic was used to analyze the data collected (t test or ANOVA)?
What were the findings?
Ask yourself: How did using an inferential statistic bring value to the research study? Did it increase the study’s application to evidence-based practice?
By tomorrow Wednesday 09/27/17, 8 pm, write a minimum of 550 words essay in APA format with a minimum of 3 references from the list in the instructions area. Include the level one headings as numbered below:
Post a cohesive response that addresses the following:
1) Identify the topic you selected in the first line of your posting. (you can choose any nursing topic from Confidentiality or Work Place Bullying or any other nursing related issue that will be easy to locate a scholarly research article on which uses a t test or ANOVA)
2) Summarize the study discussed in your selected research article and provide a complete APA citation. Include in your summary the sample, data sources, inferential statistic utilized, and findings.
3) Evaluate the purpose and value of this particular research study to the topic.
4) Did using inferential statistics strengthen or weaken the study’s application to evidence-based practice?

This is a continuation of the Course Project presented in Week 2. Before you begin, review the Course Project Overview document located in the Week 2 Resources area.
The literature review is a critical piece in the research process because it helps a researcher determine what is currently known about a topic and identify gaps or further questions. Conducting a thorough literature review can be a time-consuming process, but the effort helps establish the foundation for everything that will follow. For this part of your Course Project, you will conduct a brief literature review to find information on the question you developed in Week 2.
This will provide you with experience in searching databases and identifying applicable resources.
To prepare:
Review the information in Chapter 5 of the course text, focusing on the steps for conducting a literature review and for compiling your findings.
Using the question you selected in your Week 2 Project (Part 1 of the Course Project), You Chose “The ever increasingly high incidence of breast cancer conditions” locate 5 or more full-text research articles that are relevant to your PICOT question. Include at least 1 systematic review and 1 integrative review if possible.
Use the search tools and techniques mentioned in your readings this week to enhance the comprehensiveness and objectivity of your review.
You may gather these articles from any appropriate source, but make sure at least 3 of these articles are available as full-text versions through Walden Library’s databases.
Read through the articles carefully. Eliminate studies that are not appropriate and add others to your list as needed. Although you may include more, you are expected to include a minimum of five articles. Complete a literature review summary table using the Literature Review Summary Table Template located in this week’s Learning Resources.
Prepare to summarize and synthesize the literature using the information on writing a literature review found in Chapter 5 of the course text.
To complete:
Write a 3- to 4-page literature review that includes the following:
A synthesis of what the studies reveal about the current state of knowledge on the question that you developed
Point out inconsistencies and contradictions in the literature and offer possible explanations for inconsistencies.
Preliminary conclusions on whether the evidence provides strong support for a change in practice or whether further research is needed to adequately address your inquiry
Your literature review summary table with all references formatted in correct APA style
Note: Certain aspects of conducting a standard review of literature have not yet been covered in this course. Therefore, while you are invited to critically examine any aspect of the studies (e.g., a study’s design, appropriateness of the theoretic framework, data sampling methods), your conclusion should be considered preliminary. Bear in mind that five studies are typically not enough to reflect the full range of knowledge on a particular question and you are not expected to be familiar enough with research methodology to conduct a comprehensive evaluation of all aspects of the studies.
This part of the Course Project is due. It will also be a component in your Portfolio Assignment in this course, which is due by Day 7 of Week 10.

So here here is the initial “conflict in patient are” post in the attachment.
And this is what the question was like.
You are a Family Nurse Practitioner working in an outpatient primary care office of a large hospital system. The practice has been operating for over 15 years, and many of the administrative and clinical staff were hired when the practice opened. You have been in the practice for less than 3 months. In that short amount of time, you have witnessed several of the clinical staff have heated arguments with each other, sometimes in patient areas. Today, one of the back office assistants didn’t come to work. Unfortunately, this pattern of behavior is not unusual in this practice. Your clinical schedule is especially busy. Working without appropriate office staff will negatively influence your ability to spend time with patients, impede the flow of patients through the office, and could impact patient safety.

Discussion: Posttraumatic Stress Disorder
It is estimated that more than 6% of the U.S. population will experience posttraumatic stress disorder (PTSD) in their lifetime (National Center for PTSD, 2010). This debilitating disorder often interferes with an individual’s ability to function in daily life. Common symptoms of anxiousness and depression frequently lead to substance abuse issues and even physical ailments. For this Discussion, as you examine the Thompson Family Case Study in this week’s Learning Resources, consider how you might assess and treat clients presenting with PTSD.
· Review this week’s Learning Resources and reflect on the insights they provide.
· View the media Academic Year in Residence: Thompson Family Case Study, and assess the client in the case study.
· For guidance on assessing the client, refer to pages 137–142 of the Wheeler text in this week’s Learning Resources.
Note: To complete this Discussion, you must assess the client, but you are not required to submit a formal Comprehensive Client Assessment.
Post an explanation of your observations of the client in Thompson Family Case Study, including behaviors that align to the PTSD criteria in DSM-5. Then, explain therapeutic approaches you might use with this client, including psychotropic medications if appropriate. Finally, explain expected outcomes for the client based on these therapeutic approaches. Support your approach with evidence-based literature.
