Linear Regression

Now that you ve completed your analysis and determined the linear regression formula and r^{2}, it now time to report on the results of your study and examine your findings.

In a Microsoft Word document, respond to the following:

- Report the sample you selected and the question that was explored in the study.

- Report the r
^{2}linear correlation coefficient and the linear regression equation produced in the Excel spreadsheet.

- What would be the value of Pearson s r (simply the square root of r
^{2})?

- Would Pearson s r be positive or negative? What does this imply about the relationship between the factors in this study?

- What is the implication of any correlation found between the variables in the study you picked?

- Does this correlation imply a causal relationship? Explain.

- Are there other variables that you think should have been examined that would have improved this study or help to pinpoint what factors are causal?
