2.2.A—Calculate summary statistics from two-way tables

Calculate summary statistics from two-way tables.

• A joint relative frequency in a two-way table is a cell frequency divided by the total for the entire table.
• A marginal relative frequency in a two-way table is a row total divided by the total for the entire table or a column total divided by the total for the entire table.
• A conditional relative frequency is a relative frequency computed by restricting to a particular level, or category of interest. A conditional relative frequency can be a cell frequency in a row divided by the total for that row or it can be a cell frequency in a column divided by the total for that column.
