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. |

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 |
