How can you show who likes apples or cookies, and who has dogs or cats, all in one neat picture?
We use a two-way table, which is a chart that sorts two different choices at the same time.
How do we find our way around this grid? Let's look at the two directions.
Rows and Columns
A row is a line of boxes that goes side-to-side, like looking across the horizon.
A column is a line of boxes that goes straight up-and-down, like a tall building pillar.

What happens when a row and a column bump into each other?
Finding the Intersection
The box where a row and a column meet is called the intersection.
To find an answer, trace one finger straight across the row and another finger straight down the column until they touch.
