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.
