Using the Analysis ToolPak to create a frequency distribution

The Analysis ToolPak add-in, distributed with Excel, provides another way to calculate a frequency distribution. Start by entering your bin values in a range. Then choose Data?Analysis?Analysis to display the Data Analysis dialog box. If this command is not available, see the sidebar, “Is the Analysis Toolpak Installed?”.

In the Data Analysis dialog box, select Histogram and click OK. You should see the Histogram dialog box shown in Figure 17-8. Specify the ranges for your data (Input Range), bins (Bin Range), and results (Output Range), and then select any options. Figure 17-9 shows a frequency distribution (and chart) created with the Histogram option.

Note that the frequency distribution consists of values, not formulas. Therefore, if you make any CAUTIION changes to your input data, you need to rerun the Histogram procedure to update the results.
