# Inferential Statistics

For this discussion, you will examine inferential statistics and how they can be used to analyze data in epidemiology. Inferential statistics is different than descriptive statistics. Rather than summarizing the data, inferential statistics test hypotheses so that inferences about a population can be made. Inferential statistics are used to decide whether the outcome of the study is a result of factors planned within the design of the study or determined by chance.  With inferential statistics, probability values (p-values) are used to communicate the significance or lack of significance of the results. Choosing the best method to analyze data will depend on factors such as the research question, study design, type of variables, and the sample (Zeni, 2021).

3. Review the Chapter 5 PowerPoint(PowerPoint presentation) file.
5. Review: Navigating Statistics for Successful Project Implementation(new tab)
6. Watch the following videos:
7. Choose a problem from your practice that is of interest to you and locate in OCLS a quantitative nursing research article that addresses the problem. Examples of topics are falls, patient handoff, catheter infections, incivility, and mentoring. Use the research article to answer the questions below:
1. What was the purpose of the study?
2. What were the independent variables (IV) and dependent variables (DV)? Identify the level of measurement for both variables.
3. What was the hypothesis?
4. What inferential statistics were used to analyze the data? Describe the results.
5. Were the results statistically significant (p-value)? Why or why not?
8. Support your initial discussion post with references that are relevant, scholarly, peer-reviewed sources, or authoritative
