== SOCR Analyses Example on Fligner-Killeen Non-parametric Test. ==

This example is based on a dataset from the '''R package''' under the library '''MASS'''. The dataset's name is '''InsectSprays'''.

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.

<center>[[Image:SOCR_AnalysisActivities_Survival_Chu_081015_Fig2.gif|700px]]</center>

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

<center>[[Image:SOCR_AnalysisActivities_Survival_Chu_081015_Fig3.gif|700px]]</center>

'''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.
