Chapter 11.4, Problem 4E

To determine

To describe two ways to calculate conditional relative frequencies.

Answer to Problem 4E

Conditional relative frequencies can be found out by:

1. Dividing each joint relative frequency with the marginal relative frequency of the row.
2. Dividing each joint relative frequency with the marginal relative frequency of the column.

Explanation of Solution

Given information :

The conditional relative frequency.

Two-way tables are frequency tables that depict data of two categories, but are gathered from the same source. The entries in a two table are such that they represent data of the rows as well as the columns.

On dividing each non-total joint relative frequency with the marginal relative frequency of a row, the conditional relative frequency can be found out.

Also, on dividing the non-total joint relative frequency with the marginal relative frequency of a column, the conditional relative frequency can be obtained.
