Exploring Advanced Data Analysis

challenge yourself 8.4 In this project, you will use scenarios and a scenario summary to analyze car purchasing options. A large amount of data about car gas consumption was downloaded from https://explore.data.gov/d/9un4-5bz7 and are explained at this Web site: http://www.epa.gov/greenvehicles/Aboutratings.do. You will use custom filtering to find the data you are interested in and copy it from this very large data set to another worksheet. You will then use Advanced Filter, conditional formatting, sorting, and subtotals to further analyze this subset of data. You will manipulate a PivotTable created from the main vehicle data set. Finally, you will use Solver to solve a business problem to help you pay for your new car.

Skills needed to complete this project:

 Creating What-If Analysis Scenarios

 Creating Scenario Summary Reports

 Creating a Custom Filter  Using Advanced Filter

 Creating New Conditional Formatting Rules

 Sorting Data on Multiple Criteria

 Adding Subtotals

 Changing the Look of a PivotTable  Filtering PivotTable Data

 Activating the Solver Add-Inn

 Using Solver

1. Open the start file EX2013-ChallengeYourself-8-4. The file will be renamed automatically to include your name. Change the project file name if directed to do so by your instructor, and save it.

2. If the workbook opens in Protected View, click the Enable Editing button in the Message Bar at the top of the workbook so you can modify the workbook.

3. You want to purchase a new car. Your current car is worth $2,500 as a trade-in. The base sticker price on the car you want is $21,595. The first financing offer from the dealer is 1.9% APR for 24

months, with no cash back. The original financing offer terms are listed in cells A3:B9 on the Car

Loan worksheet. Cell B10 contains a formula with a PMT function to calculate the monthly payment.

Use what-if analysis tools to compare financing options.

4. Create scenarios to compare financing options for the car loan.

a. Create names for the following cells to make the scenarios easier to follow:

Name cell B3: Price

Name cell B4: TradeIn

Name cell B5: CashBack

Name cell B6: Loan

Name cell B8: Months

Name cell B9: APR

Name cell B10: Payment

Name cell B12: TotalCost

b. Create a scenario named Original Financing to save the original values in cells B3, B5, B8, and B9.

c. Create a second scenario named Intermediate Car. Change the values as follows:

Cell B3: 33999

Cell B5: 1500 Cell B8: 36

Cell B9: 2.4%

d. Show the Intermediate Car scenario to verify your data entry.

e. Create a third scenario named Luxury Car. Change the values as follows:

Cell B3: 56500

Cell B5: 2500

Cell B8: 60

Cell B9: 3.9%

f. Show the Luxury Car scenario to verify your data entry.

5. Create a scenario summary report to compare the results for cells B10 (the monthly payment) and B12 (the total cost of the car including interest).

6. The data in the MPG Data worksheet were downloaded from the Web site https://explore.data.gov/d/9un4-5bz7 and are explained at this Web site: http://www.epa.gov/greenvehicles/Aboutratings.do. The greenhouse gas scores range from 0 to 10, where 10 is best. The vehicles with the best scores on both air pollution and greenhouse gas receive the SmartWay designation. Use custom filtering to find cars in this data set that meet your criteria and then copy the smaller data set to another worksheet where you can work with it further.

a. Go to the MPG Data worksheet, and display the AutoFilter arrows for the data set.

b. Create a custom number filter to show only rows where the greenhouse gas score is greater than or equal to 8.

c. Create another custom number filter to show only rows where the highway MPG is greater than or equal to 35.

d. Create a custom text filter to show only rows where the Trans column contains the word Auto. e. At this point, the list of more than 2,000 cars should be filtered down to just 27 records.

f. Copy the filtered data to cell A1 in the My Car Data worksheet. Be sure to include the heading row and paste keeping the source columns widths.

7. On the My Car Data worksheet, use Advanced Filter to copy a subset of data to another location on this worksheet.

a. Copy cells A1:O1 and paste them below the data set in row 31.

b. In cell A30, type: Criteria

c. Set up the criteria in the row(s) below row 31. Find cars where the value in the Fuel column is gasoline and the value in the Hwy MPG column is greater than 35.

d. In cell A34, type: Filtered Data

e. Use Advanced Filter to find the rows that meet the criteria and copy the filtered data to another location beginning in cell A35.

f. Thirteen rows should have been copied from the main data set to cells A36:O48.

8. Format the filtered data set (cells A35:O48) as a table. Use Table Style Light 9. Be careful not to include row 34 in the table data range.

9. Insert a new table column to the left of the Greenhouse Gas Score column.

a. Copy the values from cells M36:M48 to N36:N48.

b. Type this column label in cell N35: Cmb MPG Icon

10. Apply a new custom conditional formatting rule to cells N36:N48 to show the 4 Ratings icon set. Show the icon only.

11. Sort the table first alphabetically by the values in the Model column and then by icon in the Cmb MPG Icon column so the Signal Meter With Four Filled Bars icon appears at the top and the Signal Meter With One Filled Bar icon appears at the bottom.

12. Go back to the main data set at the top of the My Car Data worksheet and add subtotals for each change in Model to calculate the average for the following: Air Pollution Score, City MPG, Hwy MPG, and Cmb MPG.

13. Collapse the data to show just the total rows.

14. Go to the MPG PivotTable worksheet. This sheet includes a PivotTable created from the data on the MPG Data worksheet.

a. Apply the Pivot Style Light 14 Quick Style to the PivotTable.

b. Display a slicer for the SmartWay field and show only data where the SmartWay value is Yes.

15. To pay for the new car, you’ve decided to start a bakery business out of your home kitchen. You have limited capital and capacity, so you need to make wise decisions about which products to bake each day. Go to the Bakery Business worksheet. Cell B1 uses a SUMPRODUCT formula to calculate profit. Carefully review the assumptions and formulas in this worksheet before entering the following Solver parameters:

a. Find the maximum possible profit (cell B1) by changing the values in cells C7:C10.

b. The working hours required (B3) must be less than or equal to the number of working hours in the day (D3).

c. The total cost of ingredients (B4) must be less than or equal to the available capital (D4).

d. For each item in the range C7:C10, the number of items baked cannot exceed the maximum capacity available per day as defined in cells F7:F10. This restriction requires four separate constraints in the Solver Parameters dialog.

e. The items in the variable cell range C7:C10 must be whole numbers.

f. There should be a total of seven constraints.

g. Run Solver and accept the Solver solution.
