SOCR Analysis - SOCR Analyses Example on the Chi-Square Contingency Table
Go to the SOCR Chi-Square Contingency Table Applet. 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.
