What is a two-way frequency table?

Back

A two-way frequency table is a statistical tool that displays the frequency of different outcomes in two categorical variables, allowing for the analysis of the relationship between them.

What is the difference between marginal and joint frequencies?

Back

Marginal frequencies are the totals for each category in a single variable, while joint frequencies are the counts for combinations of categories from both variables.

What is a conditional frequency in a two-way frequency table?

Back

A conditional frequency is the frequency of a specific category given a condition, often calculated by dividing a joint frequency by a marginal frequency.
