Description
Using the materials/references provided, please address the following:
Define and describe commonly used statistics for categorical and continuous variables to test for a statistically significant difference between two-samples or measures (e.g., chi-square, t-tests, binomial proportions, etc.). (1 page)
What is the difference between the one-sample t-test, the two-sample t-test, and the paired-sample t-test? (1 page)
Describe a type of study for each of these three types of t-tests, as well as the variable that is analyzed with each of the three forms of the t-test. (1 page)
Length: Case Assignment should be at least 3 pages in length.
References: Two references from academic sources must be included (e.g., peer-reviewed journal articles). You may use any required readings from this module for your two references. Quoted material should not exceed 10% of the total paper (since the focus of these assignments is critical thinking). Use your own words and build on the ideas of others. When material is copied verbatim from external sources, it MUST be enclosed in quotes. The references should be cited within the text and listed at the end of the assignment in the References section (APA formatting recommended).
Organization: Subheadings should be used to organize your paper according to each question.
Format: APA formatting

Define and describe each of the measures of association: OR, RR, ANOVA, and Correlations. (1 page)
Provide an example of a study that uses each of the six types of analyses (OR, RR, ANOVA, correlations, chi-square, t-tests). (1- to 2-pages)
How are OR and RR different? What types of studies use OR versus RR? (1 page)
