Unpacked Content
Knowledge
Students know:
- Characteristics of data sets that distinguish categorical data from measurement data.
Skills
Students are able to:
- Construct two-way tables for categorical data.
- Find relative frequencies for cells in the two-way tables.
- Conjecture about patterns of association in the two-way tables and explain the reasoning that leads to the conjecture.
Understanding
Students understand that:
- Organizing categorical data in two-way tables can aid in identifying patterns of association in the data.
- Relative frequencies, rather than just absolute frequencies, need to be calculated from two-way tables to identify patterns of association.
