In this assignment, you will use a spreadsheet to examine pairs of variables, using the method of linear regression, to determine if there is any correlation between the variables. Afterwards, you will postulate whether this correlation reveals a causal relationship (and why).

In this assignment, you will use a spreadsheet to examine pairs of variables, using the method of linear regression, to determine if there is any correlation between the variables. Afterwards, you will postulate whether this correlation reveals a causal relationship (and why).

Click here to open the Excel spreadsheet containing the data for this assignment.

This spreadsheet contains the data from a study that attempted to see if there is a correlation between the hours that students studied and the grade that they earned on a test. The correlation test you are about to run will help you to determine if there is, in fact, a correlation between study time and test score. If you find a strong correlation, then you will postulate whether you feel this indicates a causal relationship.

Below are instructions on how to perform this correlation test in Microsoft Excel.

In the Excel spreadsheet, perform the following operations:

  1. Save the spreadsheet to your computer.
  2. With your mouse, highlight all of the data on the spreadsheet in columns A and B.
  3. In the tabs at the top of the page, click Insert.
  4. In the Insert ribbon, in the Charts section, click Scatter. Be sure to select the option where it will just plot dots, it will be called Scatter with only Markers. If you do this right, then you’ll see a chart on the page.
  5. Now, on the chart, right-click on one of the data points (dots). Just pick a dot somewhere near the middle of the distribution.
  6. Select Add Trendline from the drop-down menu that appears when you right-click on a dot.
  7. A new menu will appear. Select Linear, select Automatic, and click the boxes next to Display Equation on chart and Display r-squared value on chart.
  8. Click Close.
  9. Now, you should see a line drawn through the dots. It will roughly cut through the middle of the dot distribution.
  10. You’ll also see the linear regression equation and r2 value displayed next to the line.

To see an example spreadsheet containing a completed analysis click here.

Now that you’ve completed your analysis and determined the linear regression formula and r2, it is now time to report on the results of your study and examine your findings.

In a Microsoft Word document, respond to the following:

  1. Report the sample you selected and the question that was explored in the study.
  1. Report the r2 linear correlation coefficient and the linear regression equation produced in the Excel spreadsheet.
  1. What would be the value of Pearson’s r (simply the square root of r2)?
  1. Would Pearson’s r be positive or negative? What does this imply about the relationship between the factors in this study?
  1. What is the implication of any correlation found between the variables in the study you picked?
  1. Does this correlation imply a causal relationship? Explain.
  1. Are there other variables that you think should have been examined that would have improved this study or helped to pinpoint what factors are causal?

For this assignment, you will submit a spreadsheet and a report. The spreadsheet will be the Microsoft Excel file containing your scatterplot and analysis. Name your Microsoft Excel file as follows: LastnameFirstInitial_M3_A2.xls.

The report will be a Microsoft Word document in which you will address all of the questions in this assignment in the form of a narrative.  Name your Microsoft Word document as follows: LastnameFirstInitial_M3_A2.docx.

In your own words, explain what it means if the correlation of 2 variables is positive, negative, or minimal (close to 0), and give an example of each.

You are in a brainstorming session at WidgeCorp, where no idea is too outrageous. You are discussing penetration in the school lunch market. Ideas around school lunch subsidies, Internet subsidies, and Internet target marketing are being discussed. As the end of the meeting, the group asks you to prove or disprove some assumptions by looking at correlations.

First, acquaint yourself with the Internet subsidy issue by reading the article Closing the Digital Divide: Internet Subsidies in Public Schoolsby Austan D. Goolsbee and Jonathan Guryan.

Next, download the file Sample Data. Based on the findings as reported in this article, prepare a chart similar to the one in the downloaded file to indicate if the correlation between Variables A and B were found to be positive, negative, or minimal.

In your own words, explain what it means if the correlation of 2 variables is positive, negative, or minimal (close to 0), and give an example of each.

How should I think about ultimate reality (Hinduism)? Is there a Supreme Being (Judaism)? Should I even think of god, letting myself be my supreme authority (Buddhism)?

The origins of Judaism and Hinduism are almost 4,000 years old. Buddhism arose from the teachings of a single Hindu teacher more than two thousand years ago. All three have changed and developed over the centuries. All three are very much alive today.

Concentrating on their current forms, compare the approaches of the three religions to the basic religious questions:

    • How should I think about ultimate reality (Hinduism)? Is there a Supreme Being (Judaism)? Should I even think of god, letting myself be my supreme authority (Buddhism)?

 

    • What is the relationship of human beings to this reality (God)?

 

    • What exactly is the concept of faith to each of these three religions? Is it the same as belief, or not? Consider all three religions and compare.

 

  • How do these concepts of the Ultimate Reality, Supreme Being or self help address the following questions: What is wrong with the world, and how can I help to fix it? What am I supposed to do with my life?

Consider the three religions, Buddhism, Hinduism, and Judaism. In an essay of approximately 700 to 800 words in length, answer the questions listed above. Be sure to use appropriate APA format for citations and to include at least one reference for each religion.
