Two-Way Tables

Front

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 in analyzing the relationship between the two variables.

Front

What is joint relative frequency?

Back

Joint relative frequency is the ratio of the frequency of a specific combination of categories to the total number of observations. It shows how often two events occur together relative to the total.

Front

How do you calculate joint relative frequency?

Back

To calculate joint relative frequency, divide the frequency of the joint occurrence by the total number of observations.

Front

What is the purpose of a two-way table?

Back

The purpose of a two-way table is to organize data to show the relationship between two categorical variables, making it easier to analyze and interpret the data.

Front

What does the total frequency in a two-way table represent?

Back

The total frequency in a two-way table represents the total number of observations or subjects surveyed.

Front

How can you find the marginal frequency in a two-way table?

Back

Marginal frequency can be found by summing the frequencies of a row or a column in the two-way table.

Front

What is the difference between joint frequency and marginal frequency?

Back

Joint frequency refers to the count of occurrences for a specific combination of categories, while marginal frequency refers to the total counts for each category, regardless of the other variable.

Front

What is a conditional relative frequency?

Back

Conditional relative frequency is the ratio of the joint frequency of a specific category to the marginal frequency of the category it is conditioned on.

Front

How do you interpret a joint relative frequency of 0.1?

Back

A joint relative frequency of 0.1 means that 10% of the total observations fall into the specific combination of categories being analyzed.

Front

What is the significance of percentages in two-way tables?

Back

Percentages in two-way tables help to understand the proportion of observations in relation to the total, making it easier to compare different categories.
