Access Free Two Way Marginal Relative Frequency (MRF) comparing a marginal frequency to the total number of responses.
Conditional relative frequency is a more complicated matter since the comparison does not use the total frequency found at the bottom right of the table, instead, it compares a joint pair of data with a marginal category of its respective row or column.

The most efficient method to represent data about the relative frequency is by using a two-way table.
Joint relative frequency is the ratio of the frequency in a particular category and the total number of data values. As a note, qualitative data is data that can't be measured through instruments; however, qualitative data can be counted. idaho high school districts .
