What is a two-way table?

Back

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

How do you read a two-way table?

Back

To read a two-way table, locate the row and column corresponding to the categories of interest, and find the intersection to determine the frequency or count.

Front

What does the term 'marginal frequency' mean in a two-way table?

Back

Marginal frequency refers to the totals found in the margins (the last row and column) of a two-way table, representing the total counts for each category.

Front

What is 'joint frequency' in a two-way table?

Back

Joint frequency is the count that appears in the body of the two-way table, representing the frequency of occurrences for a specific combination of categories.

Front

How can you calculate the total number of observations from a two-way table?

Back

To calculate the total number of observations, sum all the joint frequencies in the table.

Front

What is the purpose of using a two-way table?

Back

The purpose of using a two-way table is to organize and analyze the relationship between two categorical variables, making it easier to identify patterns and trends.

Front

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

Back

Conditional frequency is the frequency of a specific category given another category, often calculated by dividing the joint frequency by the total of the row or column.

Front

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

Back

To find the percentage of a category, divide the frequency of that category by the total number of observations and multiply by 100.

Front

What is the difference between 'row total' and 'column total' in a two-way table?

Back

Row total is the sum of frequencies across a row, while column total is the sum of frequencies down a column, both representing marginal frequencies.

How can two-way tables help in making predictions?

Back

Two-way tables can help in making predictions by analyzing the relationship between variables and identifying trends that can inform future outcomes.
