Do It Yourself!: Chi-Square Test of Independence

This applet illustrates the chi-square test of independence for Examples 14.3 and 14.4 in the text. Blue cells indicate an excess of observations relative to expected, and red cells indicate a deficit of observations relative to expected. The intensity of the color reflects the magnitude of the discrepancy. The numbers in the cells may be changed.

The above applet depicts the data for Example 14.5 in the text.

This applet with generic labels may be used for additional problems. Change any numbers in the text fields to correspond to the numbers in your problem. To update the applet, be sure to hit the Enter key after changing the numbers.
