The column means test looks at means that are presented in a row of a table and compares pairs of columns, testing whether the mean in one column is significantly different from the mean in the other column. UNICOM Intelligence Reporter - Survey Tabulation assigns an ID to each column in the test. When there is a difference between any pair of means at the chosen significance level, UNICOM Intelligence Reporter - Survey Tabulation displays the ID of the column that contains the smaller value below the cell contents of the cell that contains the larger value.

The means must be formed from a mean element in the axis rather than from mean values that are created using the Mean cell contents option. For more information 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 means test.
