The skill that covers it
What a student should be able to do
- Complete a two-way table from a description using row and column totals.
- Compute joint, marginal and conditional relative frequencies as fractions or percents.
- Compare a conditional relative frequency across rows to decide whether there is an association.
- Build a two-way table from survey results and read it critically.
