What is a two-way table?

Back

A two-way table is a statistical table that displays the frequency distribution of two categorical variables. It helps to analyze the relationship between the two variables.

Front

Define frequency table.

Front

What is a categorical variable?

Back

A categorical variable is a type of variable that can take on one of a limited, fixed number of possible values, representing different categories.
