Assignment : Correlation and Regression

A human resources (HR) manager wants to know if annual performance review scores can be predicted by the number of vacation days taken during the year and the number of dependents an employee claims.

She randomly pulls the vacation, W-2, and performance review records of twenty employees. The data is presented below.

EmployeeNumber of Vacation Days TakenNumber of DependentsOverall Performance Rating (from 1 [lowest] to 4 [highest])

Using the above data, run a correlation matrix and then run a regression analysis in Microsoft Excel that will answer the human resources (HR) manager's question.

Examine the results and consider the implications.

Write a 3- to 4-page paper based on the results and implications. Make sure to include your data printout and justify your responses.

Describe any potential ethical or legal concerns related to this research. Provide a rationale backed by authoritative references to support your position.
