In this dataset, there are two variables: count, which is quantitative, and **spray** , a factor of six groups, denoted by **A** to **F**.

The analysis steps:

**1.** As you start the SOCR Analyes Applet, click on **Fligner-Killeen Test** from the combo box in the left panel. Next, click on **Example 2** and then the **Data** tab on the top of the right panel. You will see something like below. The data have been divided into 6 columns by groups.

**2.** Click on the **Mapping** tab to map the groups you would like to include in the analysis. Select at least two groups.

**3.** Now you will click on **Compute** to let the program produce the results. Click on **Result** to view the results.

**Note**: if you happen to click on the "Clear" button in the middle of the procedure, all the data will be cleared out. Simply start over from step 1.
