Two way tables examine the relationships between two categorical variables, referred to as bivariate data. Two-way frequency tables are especially important because they are often used to analyze survey results. Two-way frequency tables are also called contingency tables.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.
