Two-way tables
A two-way table organizes counts of two categorical variables at once, like whether students have a curfew and whether they have chores, and comparing the relative frequencies in each row or column can reveal whether the two categories are associated: for example, if 30 out of 50 students with a curfew also have chores (60%), but only 10 out of 50 without a curfew have chores (20%), having a curfew and having chores look associated.
