Concept

Joint and Marginal Relative Frequencies

In a two-way frequency table, a joint relative frequency is the ratio of a joint frequency to the grand total. Similarly, a marginal relative frequency is the ratio of a marginal frequency to the grand total. Consider the following example of a two-way table.

Here, the grand total is

100 .

The joint and marginal frequencies can now be divided by

100

to obtain the

joint

and

marginal

relative frequencies. Clicking in each cell will display its interpretation.
