### SOCR Analyses Example on the Chi-Square Contingency Table

This example is based on the data taken from "Mathematical Statistics and Data Analysis" by John A. Rice, Second Edition, Ducbury Press, 1995. (page 491)

Steps:

1. Click on "Chi-Square Test Contingency Table" from the combo box in the left panel.

2. Click on "Input" button to set up table size and type in data.

3. The data need to be send to the computer for analysis. Click on the "Mapping" button to include the groups you want.

You will first see a screen like this.

The number of rows and/or columns can be changed.

We'll se 2 by 2 in our example. Enter the data. Use mouse click and tabs to move around. Note that, if you don't like the default row and column names, you can change them.

3. Now you're ready to see the results. Just click on the "Result" button.

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 and reteive the data by click an EXAMPLE button.
