A two-way table is a display of data divided into two different categories of subsets.

In the example below, the categories are
age range: with subsets for ages 0-5, 6-10, and 11-15
color preference: with subsets for various color choices

The entry at D5 (value 8) indicates that 8 children in the age range 6-10 chose yellow as their preferred color.

The sum of values across a line indicates the number of children who chose the color for that line across all age ranges.

The sum of values down a column indicates the number of children surveyed in the corresponding age range.
