Creating Formulas That Count and Sum 14<br />

FIGURE 14.7<br />

Creating a frequency distribution of test scores.<br />

Using the Analysis ToolPak to create a frequency distribution<br />

The Analysis ToolPak add-in, distributed with Excel, provides another way to calculate a frequency distribution.<br />

Start by entering your bin values in a range. Then choose Data ➪ Analysis ➪ Analysis to display the<br />

Data Analysis dialog box. If this command is not available, see the sidebar, “Is the Analysis Toolpak<br />

Installed?”.<br />

In the Data Analysis dialog box, select Histogram and click OK. You should see the Histogram dialog box<br />

shown in Figure 14.8.<br />

Specify the ranges for your data (Input Range), bins (Bin Range), and results (Output Range), and then<br />

select any options. Figure 14.9 shows a frequency distribution (and chart) created with the Histogram<br />

option.<br />

NOTE<br />

Note that the frequency distribution consists of values, not formulas. Therefore, if you make any<br />

changes to your input data, you need to rerun the Histogram procedure to update the results.<br />
