Explain how you arrived at your answer. {x | x N and x Please notice that you should be able to use the instructors live chat sessions during Week 5 to obtain the calculated values (slope, intercept, and correlation) as well as the required graph inside a second spreadsheet (I showed during Tuesday live chat how to open a second spreadsheet in the EXCEL posting) for Part III. Notice that I provided the instructions for EXCEL calculations in Parts 1 and 2 during Week 4. In case you face an issue or you receive some error message, you can closely follow the steps shown below to create the formulas inside the spreadsheet and on obtain the required values and to create the graph: Copy and paste the Task List data table from spreadsheet 1 (Part I labeled as fat) of your spreadsheet in exact location inside a new as the second spreadsheet so that the actual data would be placed between rows 2 and 253 of columns B and C. I showed during Week 5 live chat session how to add new spreadsheet to your current EXCEL spreadsheet. Then, follow the steps shown below to find the slope and intercept of the regression line, and to create the graph of scatter plot and the regression line, as required, in Part 3. PART 3 Slope 1. place the cursor inside an empty cell to right side of the data table in spreadsheet Part III. 2. Open formula tab at the top of the spreadsheet. 3. Open more functions tab at the top of the spreadsheet. 4. Open statistical tab from the menu that opens. 5. Select and open SLOPE tab from a vertical menu that opens. 6. Type in exactly C2:C253 inside the top window labeled as Known_Ys 7. Type in exactly B2:B253 inside the lower window labeled as Known_Xs 8. Left click on OPEN tab of the window. 9. Move the cursor to a remote cell location (a blank cell). 10. Finally, move and place the cursor inside the original cell location for slope. You should be able to see the correct value for the slope of the regression line. Intercept For Y-intercept of the regression line, follow the steps stated above by selecting INTERCEPT tab from the vertical menu, in Step 5 (above). Correlation To find the correlation coefficient between body fat and body weight, follow the 10 steps shown above including: 5. Select and open CORREL tab from a vertical menu that opens. 6. Type in exactly C2:C253 inside the top window labeled as Array 1. 7. Type in exactly B2:B253 inside the lower window labeled as Array 2. Graph In order to find the graph in Part 3 (inside Spreadsheet III), follow these steps: 1. Place the cursor in an empty area (below calculated regression and correlation). 2. Place the cursor in the cell location B2 (top cell for body fat) by holding down the left click of the mouse. Then, drag and cover the entire data for columns B and C (B2 to B253 and C2 to C253) so that you can see shaded area inside this long window. 3. Open the Inset tab at the top of the spreadsheet. 4. Open the Scatter tab below the insert tab. 5. Select and open the top left window (with picture of scattered points). 6. You should be able to see the graph of scattered points open in a large window. 7. Move the cursor to the rectangle at the top labeled as Chart Layouts . 8. Place the cursor on a small arrow on Chart Lay out looking downward. Open that arrow with left click of your mouse. Then, select the square tab at the intersection of third row and third column (labeled as Layout 9 . Press on left click to open that tab. 9.

Assignment 2: Linear Regression
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).
Clickhere 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 a student studies 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, clickInsert.
4.In the Insert ribbon, in the Charts section, clickScatter. Be sure to select the option where it will just plot dots, it will be calledScatter with only Markers. If you do this right, then youll 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.SelectAddTrendline from the drop-down menu that appears when you right-click on a dot.
7.A new menu will appear. SelectLinear, selectAutomatic, and click the boxes next toDisplay Equation on chart andDisplay r-squared value on chart.
9.Now, you should see a line drawn through the dots. It will roughly cut through the middle of the dot distribution.
10.Youll also see the linear regression equation and r2value displayed next to the line.
To see an examplespreadsheet containing a completed analysis clickhere.
Now that you ve completed your analysis and determined the linear regression formula and r2, it 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.
2.Report the r2 linear correlation coefficient and the linear regression equation produced in the Excel spreadsheet.
3.What would be the value of Pearson s r (simply the square root of r2)?
4.Would Pearson s r be positive or negative? What does this imply about the relationship between the factors in this study?
5.What is the implication of any correlation found between the variables in the study you picked?
6.Does this correlation imply a causal relationship? Explain.
7.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?
For this assignment, you will submit a spreadsheet and a report. The spreadsheet will be the Microsoft Excel file containing yourscatterplot 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.
