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 total in a two-way table represent?

Back

The total in a two-way table represents the sum of all frequencies for a particular category or the overall total of all observations.

Front

How can you find the total number of people with a specific characteristic in a two-way table?

Back

To find the total number of people with a specific characteristic, sum the frequencies in the corresponding row or column.

Front

What is the purpose of using two-way tables in statistics?

Back

Two-way tables are used to summarize and analyze the relationship between two categorical variables, making it easier to identify patterns and trends.

Front

What is a marginal total in a two-way table?

Back

A marginal total is the sum of the frequencies in a row or column, representing the total count for that category.

Front

How do you calculate the joint frequency in a two-way table?

Back

The joint frequency is calculated by counting the number of occurrences that fall into the intersection of a specific row and column.

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 count for a single category.

Front

How can you determine the percentage of a specific category in a two-way table?

Back

To determine the percentage, divide the frequency of the specific category by the total number of observations and multiply by 100.

Front

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

Back

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