As you see, the Analysis ToolPak add-in brings a great deal of functionality to Excel. These procedures have
limitations, however, and in some cases, you may prefer to create your own formulas to do some calculations.
Installing the Analysis ToolPak Add-in
The Analysis ToolPak is implemented as an add-in. Before you can use it, you need to make sure that the
add-in is installed. Click the Data tab. If you see an Analysis group, with a Data Analysis command,
then the Analysis ToolPak is installed. If you can’t access Data ➪ Analysis ➪ Data Analysis, install the addin
by following these steps:
1. Choose Office ➪ Excel Options to display the Excel Options dialog box.
2. In the Excel Options dialog box, click the Add-Ins tab.
3. At the bottom of the dialog box, select Excel Add-Ins from the Manage drop-down list and
click Go. Excel displays the Add-Ins dialog box.
4. In the Add-Ins dialog box, place a check mark next to Analysis ToolPak.
5. Click OK to close the Add-Ins dialog box.
Using the Analysis Tools
Using the procedures in the Analysis ToolPak add-in is relatively straightforward, as long as you’re familiar with
the particular analysis type. To use any of these tools, you choose ➪ Data ➪ Analysis ➪ Data Analysis, which
displays the dialog box shown in Figure 38.1. Scroll through the list until you find the analysis tool that you
want to use and then click OK. Excel displays a new dialog box that’s specific to the procedure that you select.
