For this discussion forum, refer to the Excel file Discussion 9-1 Data Set that contains information on the following:

Identify the worksheet (tab) that matches the first letter of your LAST name (i.e., if your last name were “Fudd” you would use the data from the “F” tab). This will be the source data you will use to answer your remaining questions for this initial post.

From your source data: What is the linear correlation coefficient?

Using the linear correlation coefficient obtained in step 2 and at a level of significance of 0.05, is there sufficient evidence to support the claim of linear correlation between the two variables? Explain. (Hint: In the Excel file you used to obtain the source data, there is a worksheet/tab named Critical Values. You will need to use it to support your claim on this part of the discussion).

Discussion 10.2: Relative Risk, Odds Ratio, and Epidemiology

Define epidemiology, risk ratio, and odds ratio, and describe the three basic types of epidemiological studies. Provide examples of each (i.e., show the calculations provided in your research). Why are these calculations essential in the healthcare field?

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
