Learning Goal
Part of: Summarize, represent, and interpret data on two categorical and quantitative variables — 1 of 2 cluster items
Summarize categorical data in two-way frequency tables
**HSS.ID.B.5**: Summarize categorical data for two categories in two-way frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data.

HSS.ID.B.5: Summarize categorical data for two categories in two-way frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data.
What you'll learn
- Construct a two-way frequency table from raw paired categorical data, including row totals, column totals, and the grand total
- Compute joint, marginal, and conditional relative frequencies and distinguish them by their denominators
- Interpret each type of relative frequency as a contextual statement ("out of whom is this a percentage?")
- Recognize a possible association between two categorical variables by comparing conditional relative frequency distributions
