The chi-square test is an appropriate bivariate test when you have:

Question 1 options:

	Two continuous variables
	Two nominal variables
	A nominal variable and a continuous variable

Question 2 (1 point)

The simplest bivariate chi-square table displays the relationship between two grouped variables, each of which has two values. In each of the four cells of that table, there is a number tells how many individuals are in that cell. Those numbers are:

Question 2 options:

	The row marginals
	The column marginals
	The observed frequencies
	The expected frequencies

Question 3 (1 point)

The big calculation that you do when you test a hypothesis using the chi-square test is the calculation of:

Question 3 options:

	The row marginals
	The column marginals
	Chi-square critical
	Chi-square obtained

Question 4 (1 point)

You use Appendix C of your text ("Distribution of Chi-Square) to find:

Question 4 options:

	The row marginals
	The column marginal
	Chi-square critical
	Chi-square obtained

Question 5 (1 point)

For the chi-square test, you reject the null hypothesis if:

Question 5 options:

	The column marginal > row marginals
	Chi-square obtained > chi-square critical
	Chi-square obtained < chi-square critical
