Which of the following statements is FALSE about cross-tabulation?

A. It is the primary form of data analysis in some marketing research projects.

B. It is used to determine if differences exist among sub-groups of the total sample.

Question 12 of 20

Which of the following statements about the Chi-square test is FALSE?

A. When the differences between observed and expected frequencies are large, one must accept the null hypothesis.

B. The larger the Chi-square, the more related the two variables are.
