To describe two ways to calculate conditional relative frequencies.

Answer to Problem 4E
Conditional relative frequencies can be found out by:
- Dividing each joint relative frequency with the marginal relative frequency of the row.
- 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.
