# Statistics > Multinomial > Cross Tabulation and Chi-Square

This utility performs cross tabulation and shows the joint distribution of two variables given individual observations and optionally the frequency of each observation. The joint distribution is displayed in a contingency table, which can be stored in a datasheet for further processing. The option to perform a Chi-square test on the contingency table is also provided.

To use this utility, you will need to provide the observations in two columns (the values of the first variable in one column, and the corresponding values of the second variable in a second column). You may optionally provide the frequency corresponding to each observation in a third column.

### Dialog Inputs

- Select the columns containing row and column labels of the observations in the provided drop-down menus.
- If frequencies of the observations are available, select the column containing the frequencies in the provided drop-down menu.
- To perform a Chi-square test, select the coresponding checkbox and provide the significance level of the test.
- To store the resulting contingency table in a new datasheet, select the corresponding checkbox.
