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

Middle EasternWomen 2005The 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.
StrengthsIn 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.
Middle EasternWomen 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 SoldUnits ProducedMaterial Cost per UnitAdvertisingEtc.
Middle EasternWomen 2005It 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.
Middle EasternWomen 2005Let’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
Middle EasternWomen 2005In 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.
Middle EasternWomen 2005Other 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/Unit2-Input Data Table
Middle EasternWomen 2005Summary 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
Middle EasternWomen 2005Summary 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).
Middle EasternWomen 2005Then…
Excel executes Excel executes the formula as many times as there are input values in the data table.
For each valueFor 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 iterationFor each iteration, Excel records the result of the formula (the objective) in the data table results matrix.

An Introduction to the Excel Pivot Table
Middle EasternWomen 2005What 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.
Middle EasternWomen 2005Duke 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.

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.
Middle EasternWomen 2005Questions
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?
