Data Analysis: Examine different types of statistics and statistical tests assignment

Data Analysis
Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.

—Lewis Caroll, Jabberwocky (from Through the Looking Glass)

Data Analysis: Examine different types of statistics and statistical tests essay assignment

It might be fun to read through the nonsense syllables of the poem, Jabberwocky, but, for those who are new to statistics, looking at statistical results can feel like trying to read and garner meaning from an unfamiliar language. McNemar’s test, Cochran’s Q, ANOVA, and the Kruskal-Wallis H test may sound like something in another language, but they are all examples of statistical tests used to analyze quantitative data. Though the topic of statistics can seem intimidating and overwhelming, as a nurse, you can benefit from becoming familiar with the types of statistical tests, knowing when they are used, and understanding what they measure. Few nurses spend time calculating statistical significance using long columns of data and complex formulas, but nurses will find it useful, as they review resources for evidence-based practice, to have an acquaintance with the most commonly used statistical tests.
