How do you find the relative frequency of a category in a two-way frequency table?

Back

Divide the frequency of the category by the total number of observations and multiply by 100 to get the percentage.

What does it mean if a two-way frequency table shows a high relative frequency for a category?

Back

A high relative frequency indicates that a large proportion of the total observations fall into that category, suggesting a strong preference or trend.
