Using Data Tables for Sensitivity Analysis

• Data Tables allow you to quickly see how various model outputs relate to different values of key inputs

• Creation of Data Tables is also covered in the XLDemos.doc tutorial that I made available last year and is available from our course web (Class 1)

• 1-Way Data Tables allow you to view multiple outputs for one changing input– Ex: How are total cost, total revenue, and profit affected by

changing enrollment values?

• 2-Way Data Tables allow you view one output for two changing inputs– Ex: How does profit change for various combinations of

enrollment and capitation rates?

Getting Ready for 1-Way Data Table

Create range of values for the input variable of interest

In the cell that is one column to the right and one row above the first input value

(0 in this example), put a formula reference to the cell containing the

output you are interested in (total cost in this example).

Repeat for multiple outputs

Select entire range from B32:F33Select Data | Table... from

the menu

• We are telling Excel to take each enrollment value in the COLUMN of values in B33:B53 and substitute it into cell E6.– since our enrollment values run down a column, we just fill in the

Column input cell value

• Then the spreadsheet gets recalculated which updates the value in C32.

• Excel takes the value in C32 (total cost in this case) and puts it next to the corresponding enrollment value.

Specifying the Data to Analyze

B21 is the capitation rate

and E6 is enrollment
