What is a Two-Way Relative Frequency Table?

Back

A Two-Way Relative Frequency Table displays the relative frequencies of two categorical variables, showing how often each combination of categories occurs in relation to the total.

Front

How do you calculate relative frequency?

Back

Relative frequency is calculated by dividing the frequency of a specific category by the total frequency of all categories.

Front

What does a relative frequency of 29% indicate?

Back

Front

How do you find the percentage of a specific lunch order in a Two-Way Relative Frequency Table?

Back

You divide the number of that specific lunch order by the total number of lunch orders and multiply by 100.
