In this table, "Category A" and "Category B" represent two different categorical variables, while "Group 1" and "Group 2" represent the occurrences of these variables in different groups. The numbers in the cells represent the frequencies or observations in the corresponding categories. This table can be used to examine relationships or independence between the two variables, for example, using a Chi-Square test.
