Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). A joint relative frequency is the ratio of a frequency that is not in the total row or the total column to the total number of values or observations. Upper Saddle River, NJ: Prentice-Hall, Chapter 4.
To find a joint relative frequency, divide a data cell from the innermost sections of the two-way table (non-total) by the total frequency. In the table, the inner cells represent the joint relative frequency.
