Score:Week 5 Correlation and Regression

<1 point>1.    Create a correlation table for the variables in our data set. (Use analysis ToolPak or StatPlus:mac LE function Correlation.)

a. Reviewing the data levels from week 1, what variables can be used in a Pearson's Correlation table (which is what Excel produces)?

b. Place table here (C8):

c.Using r = approximately .28 as the signicant r value (at p = 0.05) for a correlation between 50 values, what variables are

significantly related to Salary?

To compa?

d.Looking at the above correlations - both significant or not - are there any surprises -by that I 

mean any relationships you expected to be meaningful and are not and vice-versa?

e.Does this help us answer our equal pay for equal work question?

<1 point>2Below is a regression analysis for salary being predicted/explained by the other variables in our sample  (Midpoint,

 age, performance rating, service,  gender, and degree 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.)

Plase interpret the findings.

Ho: The regression equation is not significant.

Ha: The regression equation is significant.

Ho: The regression coefficient for each variable is not significant  Note: technically we have one for each input variable.

Ha: The regression coefficient for each variable is significant  Listing it this way to save space.

Note: since Gender and Degree are expressed as 0 and 1, they are considered dummy variables and can be used in a multiple regression equation.

Interpretation:

For the Regression as a whole:

What is the value of the F statistic: 

What is the p-value associated with this value: 

Is the p-value <0.05?

Do you reject or not reject the null hypothesis: 

What does this decision mean for our equal pay question: 

For each of the coefficients:InterceptMidpointAgePerf. Rat.ServiceGenderDegree

What is the coefficient's p-value for each of the variables: 

Is the p-value < 0.05?

Do you reject or not reject each null hypothesis: 

What are the coefficients for the significant variables?

Using only the significant variables, what is the equation?Salary =

Is gender a significant factor in salary:

If so, who gets paid more with all other things being equal?

How do we know? 

<1 point>3Perform 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.

If so, who gets paid more with all other things being equal?

How do we know? 

<1 point>4Based on all of your results to date, 

Do we have an answer to the question of are males and females paid equally for equal work?

If so, which gender gets paid more? 

 How do we know?

Which is the best variable to use in analyzing pay practices - salary or compa?  Why?

What is most interesting or surprising about the results we got doing the analysis during the last 5 weeks?

<2 points>5Why 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?

See comments at the right of the data set.
