Description

I need statistics help. The class is BUS 308: Statistics for Managers... I need help with the week 5 assignment. I have it in an excel spreadsheet with the data tables. Here are the questions: 

  1. Create a correlation table for the variables in our  equal_pay___student_rev_4_3__1_-2.xlsx. (Use analysis ToolPak or the StatPlus:mac LE software function Correlation.)
    1. Interpret the results. What variables seem to be important in seeing if we pay males and females equally for equal work?
  2. Below is a regression analysis for salary being predicted/explained by the other variables in our sample  (Mid, age, ees, sr, raise, and deg variables.) 
    Note: since salary and compa are different ways of expressing an employee’s salary, we do not want to have both used in the same regression.
  3. Perform a regression analysis using compa as the dependent variable and the same independent variables as used in question 2.  Show the result, and interpret your findings by answering the same questions.
    Note: be sure to include the appropriate hypothesis statements.
  4. Based on all of your results to date, is gender a factor in the pay practices of this company?  Why or why not? Which is the best variable to use in analyzing pay practices - salary or compa? Why?
  5. Why did the single factor tests and analysis (such as t and single factor ANOVA tests on salary equality) not provide a complete answer to our salary equality question? What outcomes in your life or work might benefit from a multiple regression examination rather than a simpler one variable test?

The analysis tool pak has been removed from Excel for Windows, but a free third-party tool that can be used (found on an answers Microsoft site) is: http://www.analystsoft.com/en/products/statplusmacle Like the Microsoft site, I make cannot guarantee the program, but do know that Statplus is a respected statistical package.
