What is the difference between a chi-square test for two-way tables and a chi-square test for a goodness-of-fit test?
A)Both tests are the same.
B)The chi-square test is used to compare categorical variable distributions between populations and the goodness-of-fit test is used to compare a sample from one population with a hypothesized distribution.

The chi-square test for two-way tables is used to compare the distribution of two categorical variables within a sample, while the chi-square goodness-of-fit test is used to compare the distribution of one categorical variable in a sample to a hypothesized distribution. Therefore, B is the correct choice as it accurately distinguishes between the two types of chi-square tests.
