In this case, you insert the range B2:E9 in the Input Range field (of the dialog box of Figure 2) and select the Columns radio button. Suppose, by way of example, this data consists of a 4 × 8 array representing 4 treatments as in Figure 3. The Input Range consists of the Excel range where the data elements to be analyzed are stored. You will now be presented with the dialog box shown in Figure 2.įigure 2 – Dialog box for Anova: Single Factor option Fields

Now suppose by way of example that you choose Anova: Single Factor.
