After reading the background material and conducting your own research, you will write an essay discussing the appropriate time a safety professional might use a t-test and a correlation coefficient. You will also need to include examples to support your answer. Additionally, discuss how you would interpret the output of each analysis (i.e., what are you looking for? What does -.XX mean in comparison to .XX when you use EXCEL for correlation?) Include enough information to demonstrate your understanding of the material. Format the 3-5 pages double-spaced essay using Word or a compatible word processing application with 1″ margins and 12-point Times New Roman font following APA (6thed.) style.
