The column proportions test looks at the rows of a table independently and compares pairs of columns, testing whether the proportion of respondents in one column is significantly different from the proportion in the other column. The proportion is the count in the cell divided by the base for the column. For details about the types of tables that are suitable for this test and what happens when there is nesting or concatenation, see Details and restrictions of the column proportions test.

UNICOM Intelligence Reporter - Survey Tabulation automatically assigns a one-character ID to each column in the test. When there is a difference between any pair of proportions at the chosen significance level, UNICOM Intelligence Reporter - Survey Tabulation displays the ID of the column that contains the smaller proportion below the cell contents of the cell that contains the larger proportion.
