11/28 Chi-Square Goodness of Fit Test(11.1) ·  Know how to compute expected counts, conditional distributions, and contributions to the chi-square statistic.

·  Check the Random, Large sample size, and Independent conditions before performing a chi-square test.

· Use a chi-square goodness-of-fit test to determine whether sample data are consistent with a specified distribution of a categorical variable.

· Examine individual components of the chi-square statistic as part of a follow-up analysis.

HW: Ch. 11 Exercises #1, 3, 5, 7,  11, 15, 17

Barron’s p. 409, #1

11/29 Chi-Square Test for Homogeneity(11.2) · Use a chi-square test for homogeneity to determine whether the distribution of a categorical variable differs for several populations or treatments.

· Interpret computer output for a chi-square test based on a two-way table.·        Examine individual components of the chi-square statistic as part of a follow-up analysis.

· Show that the two-sample z test for comparing two proportions and the chi-square test for a 2-by-2 two-way table give equivalent results

11/30 Chi-Square Test for Independence(11.2)  · Check the Random, Large sample size, and Independent conditions before performing a chi-square test.

·  Use a chi-square test of association/independence to determine whether there is convincing evidence of an association between two categorical variables.

· Interpret computer output for a chi-square test based on a two-way table.
