4. Middle Eastern Women 2005 I had a background in programming prior to business school but I still learned quite a few new things in Excel that I hadn't used before. Marla McClure, MBA 2004 The Pivot Table skills I picked up are absolutely invaluable in my summer internship. I’m analyzing a sales database using Excel and I would be beating myself in the head with simple math functions by now without Pivot Tables. They really saved me! Tera Ferguson, MBA 2003 I learned enough Excel at Fuqua to take a number of finance courses that required advanced Excel spreadsheet modeling. I put many of my newly acquired Excel skills to work during my summer internship in media strategy. Dhanusha Sivajee, MBA 2004

10. Middle Eastern Women 2005 Key Excel Forecasting Tools  Series Edit, Fill, Series: Predict trends linearly or exponentially  Functions specifically for forecasting FORECAST, TREND, GROWTH, LINEST, LOGEST  Regression analysis  Data Tables  Scenarios  Solver

11. Middle Eastern Women 2005 The Excel Data Table  For forecasting, sensitivity analysis  How it works: Summarizes how a range of changes in one or more model variables affects critical values in the model. Strengths In a single operation (i.e., running the Data Table), substitute any number of different values for a particular model variable, tracking how the change affects some other critical model value. Display all the critical model value results together, in a compact format.

12. Middle Eastern Women 2005 An example for which a Data Table might be useful for forecasting See the file ForecastingTools.xls You might want to know how changing certain model values affects Operating Income, the bottom line. For example: Price per Unit Units Sold Units Produced Material Cost per Unit Advertising Etc.

13. Middle Eastern Women 2005 It would be very inefficient… …to attempt to enter directly into the model the many possible values you want to test and keep track of the bottom line for each case. The Data Table is the perfect tool to use instead.

14. Middle Eastern Women 2005 Let’s review How does changing Price per Unit affect Operating Income, the bottom line? Specifically, what is our break- even point for Price per Unit? SEE

15. Middle Eastern Women 2005 In a compact tabular format, a Data Table analysis shows the effect of multiple Price per Unit values on Operating Income and the break-even point. What’s important here? Using a Data Table, one can test a range of possible Price/Unit values on the bottom line in a single operation… …instead of having to test each Price/Unit value by entering each value in the model one by one.

16. Middle Eastern Women 2005 Other examples: How different model values affect Operating Income  Units Sold: 900, 950, …1400  Mat. Cost/Unit: $20, $21, …$30  Both Units Sold and Material Cost/Unit 2-Input Data Table

17. Middle Eastern Women 2005 Summary of using a data table  Plan Identify your model’s objective. Decide what key model value(s) (decision variables) you want to vary. They become data table inputs.  Set up Establish a range of values for the decision variable(s). Identify the model formula(s) that directly or indirectly use those values and that show the effect of the varying decision variables. Follow Excel’s data table setup requirements.  Execute Run the Data Table. Skip execution details

18. Middle Eastern Women 2005 Summary of Data Table Execution  Select the table range.  From the Data Menu Data, Table Complete the Table dialog. If data table inputs are arranged down the left column, identify the Column input cell. This is the cell that holds the model value to be varied (the decision variable).

19. Middle Eastern Women 2005 Then…  Excel executes Excel executes the formula as many times as there are input values in the data table.  For each value For each data table input value Excel substitutes that value into the data table formula (which comes from the model or references the model formula cell).  For each iteration For each iteration, Excel records the result of the formula (the objective) in the data table results matrix.

22. Middle Eastern Women 2005 What is a Pivot Table? An interactive table That can quickly summarize large amounts of numeric Excel list- format data. Use to analyze related totals, choosing from a variety of summary operations. Each column or field in the list of data becomes a PivotTable field that summarizes multiple rows. Rotate (Pivot) Rotate a Pivot Table’s rows and columns to see different summaries of the source data. Display details Display details for areas of interest.

23. Middle Eastern Women 2005 Duke MBA students’ view of the Pivot Table The opinion of students taking the Information Management elective that covers the Excel Pivot table… The Pivot Table is consistently rated  The most useful topic covered in the course. and  The Excel data management tool students think they will use most often on the job.

25. Middle Eastern Women 2005 Source data used for Pivot Table examples in the Microsoft article.

26. Middle Eastern Women 2005 The sample file we’ll use DemoPivotTable.xls

27. Middle Eastern Women 2005 Sales person Product category Product name My sample data in that file. Worksheet: Sample Data The data is from Microsoft’s NorthWind sample business, which imports and exports exotic foods.

28. Middle Eastern Women 2005 Questions  Why use a Pivot Table to analyze this data? There are 8,620 records in the list. Other Excel tools (filter, subtotal) might be useful but less powerful.  Using a Pivot Table, what kinds of questions can we answer about the data? Examples: What products are in the “Condiments” category? What quantity of each product in this category has sold? What is the sum of all quantities sold in this category? Which 3 sales people sold the most in the “Produce” category? What are product sales in particular categories by quarter?
