Get NURS 8200 Week 8: Quantitative Methods: Nonparametrics essay assignment help
Think back to the material you learned in Week 5 about t tests and analysis of variance (ANOVA). Recall that these two types of parametric tests are used to examine the differences in the means of data sets to determine the relationships between variables. For example, when diagnosed with diabetes, does participating in a nutritional program improve weight loss and reduce blood sugar levels? You may also recall that parametric tests assume normal distributions and equal variations among data sets. A limitation of parametric tests lies in the reality that not all experimental data follow these patterns.
NURS 8200 Week 8: Quantitative Methods: Nonparametrics essay
Because of this, nonparametric statistical methods were developed to analyze data sets that do not follow normal patterns of distribution and do not have consistent variation. There are many types of nonparametric methods that are useful in different situations and for different purposes. This week, you examine the application of nonparametric statistical analysis methods.
You will also begin working to complete the CITI Program human subject’s protection training course. As you know, there are many ethical considerations when conducting research, and Walden University requires that all students complete this training prior to conducting any research activities.
Researchers must make informed choices about the type of statistical analysis that best addresses the research question. For the past several weeks, you have been considering how and when a particular statistic should be employed. This week, you have focused on the use of nonparametric tests.
Nonparametric methods are useful to researchers in performing statistical analyses of quantitative data sets that do not follow normal distributions and that have inconsistent variation. Nonparametric methods are often applied when ordinal-level data are collected and, as such, rely on fewer assumptions than their parametric counterparts.
In this Discussion, you examine the two articles in this week’s Learning Resources, both of which employ nonparametric methods of statistical analysis. In addition, as the final week of exploring quantitative statistics, you consider which statistical method is most frequently used in your area of nursing practice.
