Teaching guide

What students learn

Construct two-way tables and discuss the possible relationship between categorical variables.

How to teach it

Organise paired categorical data in a two-way table, compare the counts or proportions across rows and columns, and discuss any relationship.

Worked example

A survey of 48 students found: 11 students both own a pet and have a sibling. 15 students own a pet but do not have a sibling. 8 students do not own a pet but do have a sibling. 14 students neither own a pet nor have a sibling. How many students both own a pet and have a sibling?

Answer: 11

Why: read directly from the survey description

Generated and checked in code, so it is correct.

Watch out for

Comparing raw counts when the group sizes differ instead of comparing proportions.
