SOCR Analyses Example on Kolmogorov-Smirnoff Test.
This example is based on a dataset from the R package under the library MASS. The dataset's name is oats.
The quantitative variable Y (yields of oats field) is grouped by three varieties (the categorical varible here), Victory, Golden.rain and Marvellous.
The analysis steps:
1. As you start the SOCR Analyes Applet, click on Kolmogorov-Smirnoff Test from the combo box in the left panel. Next, click on Example 4 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 two groups.
3. Now you will click on Compute to let the program produce the results. Click on Result to view the results.
4. Click on Graph to view plots.
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.
