Unlike a regular two-way frequency table, a relative frequency table will allow us to account for the differences in data. When frequencies are turned into percentages or ratios, they are called relative frequencies. We can express relative frequencies as decimal numbers between 0 and 1, as fractions, or as percentages.Association plot for two-way tables.
