You are in charge of conducting an analysis for your organization to discover if there is a relationship between an employee’s performance rating and the number of sick days they take each year. Your coworker has already collected the data, and they are ready for you to analyze.
Review the data that your coworker collected in the Analysis of Correlation Test Data Spreadsheet.
First, plan your analysis. Second, conduct your analysis. Third, describe your analysis.

Analysis Procedures: What did you do to conduct your analysis?
Part 3: Results and Discussion
