Understanding how research designs contribute to the quality of a study is essential for being able to analyze resources when conducting a literature review or locating evidence for practice. Support evidence-based nursing practices: The nursing profession is mostly based on … Someone might perform a statistical analysis of patient outcomes based upon how many patients a nurse cares for or based upon how many hours a nurse works. By Day 3 Post a summary of your search. Use at least one database for each of the three levels of filtered information and at least one unfiltered database. However, the application of statistics is both an art and a science and should not be used as the sole basis for making decisions. If there is low validity in a study, it usually means that the research design is flawed and the results will be of little or no value. Statistical knowledge helps you use the proper methods to collect the data, employ the correct analyses, and effectively present the results. Describe the data and the results of any statistical tests or analyses presented in the article. Most nurses need only a foundational understanding of statistical tools and terminology to … 8 What makes her story unique is that prior to her death, cells from her tumor were removed and successfully grown in a petri dish. Be sure to format properly within content of post. Researchers should consider their research questions and select the most suitable theory or model, which then serves as a foundation for the research design. Together, theories and models provide an understanding of the world and allow researchers to explore it in meaningful ways. References Review the information on different qualitative research designs in Chapter 21 of your course text. Locate the journal Qualitative Health Research in the Sage Premier database in the Walden Library. Thomas L, Juanes F. The importance of statistical power analysis; an example from Animal Behaviour. To this end, you will be assigned to a group by Day 1 of this week. Describe the data and the results of any statistical tests or analyses presented in the article.

What explanation did they give to support their conclusions? Pay particular attention to Table 2 in the article, Study Design in Medical Research.Revisit the 5 articles that you identified in Part 2 of the Course Project. Consider strategies that could be used to strengthen the studys internal validity and how this would impact the three other types of validity. Although the culturing of her cells has been pivotal for advancing research, strong ethical concerns later arose about using these cells without patient or family approval.This weeks readings describe historical examples of unethical research, such as a study of syphilis among African-American men in which treatment was withheld and a study in which live cancer cells were injected into elderly patients. Week 5 discussion Quantitative Research Designs In order to find the best information on a topic, not only should you develop a question and search for resources, but you should also know how to analyze the value of the resources that you identify. Describe what topic you selected, the search term(s) that you used, and the number of results found at each level of the hierarchy. Compare the types of information found in the articles from different levels and the value of the information from each level. Although the actual approach to gathering information may vary, for either research design, researchers need to plan in advance how the data will be gathered, reported, and stored, and they need to ensure that their methods are both reliable and valid. This weeks readings describe historical examples of unethical research, such as a study of syphilis among African-American men in which treatment was withheld and a study in which live cancer cells were injected into elderly patients. One is to analyze a trend in the vital statistics of a particular patient. By Day 6 Respond to at least two of your colleagues on two different days using one or more of the following approaches: Ask a probing question, substantiated with additional background information, and evidence. Identify the barrier you selected from the article and explain how this barrier could be overcome within your organization. Often, the availability of information is not the concern, but rather nurses struggle with how to convey the evidence to others and change practices to better reflect the evidence. This is the culmination of the research process in which all of the research methods and designs can be synthesized into a meaningful conclusion. What additional research could be done to build on these findings and gain a fuller understanding of the question? Statistics involves making decisions, and in the business world, you often have to make a quick decision then and there.Using statistics, you can plan the production according to what the customer likes and wants, and you can check the quali… How do you know if the tasks were based on research?What questions have you thought about in a particular area of care such as a procedure or policy?

Although the articles selected for abstraction in Evidence-Based Nursing have already been appraised, and only the highest quality research selected, practitioners still need basic skills to identify and interpret methodologically sound research. In fact statistical methods are so closely connected with human actions and behaviour that practically all human activity can be explained by statistical methods. Animal Behaviour. By understanding statistical power, nurses at all levels will become better consumers of sound scientific studies. Statistics allows you to understand a subject much more deeply. What makes her story unique is that prior to her death, cells from her tumor were removed and successfully grown in a petri dish. The arithmetic mean, more commonly known as “the average,” is the sum of a list of numbers divided by the number of items on the list. Week 10 discussion Weighing the Evidence When conducting original research, the final step researchers must complete is weighing the evidence and interpreting the meanings of their data, statistics, and analyses. Four different aspects of validity should be considered when reviewing a research design: statistical conclusion validity, internal validity, construct validity, and external validity. Descriptive statistics is that branch of statistics which deals with concepts and methods concerned with summarization and description of the important aspects of numerical data. Summarize main points presented in post Aim for 5 sentences in summary. In some data sets, the mean is also closely related to the mode and the median (two other measurements near the average). Expand on your colleagues postings by providing additional strategies for addressing barriers to EBP based on readings and evidence. Week 4 discussion Ethical Dimensions of Research Studies In the best-selling book, The Immortal Life of Henrietta Lacks (Skloot, 2010), the author highlights the true story of an African-American woman who died in 1951 from cervical cancer.

Review the scenario and formulate at least five questions that you could use to evaluate patient satisfaction. You also consider strategies for selecting an appropriate research design.To prepare:Review the information in the course texton quantitative research designs. In this stage, researchers should formulate explanations for what their data indicates, determine whether the data answers their initial research question, identify areas of uncertainty, and consider directions for further research.In this Discussion, you focus on one of the research articles that you identified for Part 2 of the Course Project (Literature Review). We have worked hard to get to this point. As in the field of nursing it can be used to calculate the arithmetic mean of the number of people who get examined each day and in the same manner the record can be maintained for a week, mint or even a year. Discuss why it is important for nurses to understand the basics of these statistical methods investigate strategies for overcoming barriers to implementing evidence-based practice (EBP). There are different ways to evaluate resources, such as using the hierarchy of evidence, which you explored in Week 4 of this course. Use the Groups link on the left navigation bar to collaborate with your group. Week 2 discussion Literature Searches An important step in the EBP process is reviewing the current body of literature to better understand the subject or topic in which you are interested.
