Key Facts
- Two-way Table: Shows frequencies for two categorical variables
- Rows represent one variable, columns represent another
- Joint Frequency: Number in each cell (intersection of row and column)
- Marginal Frequency: Row totals and column totals
- Grand Total: Sum of all frequencies
- Can calculate probabilities directly from the table
