What is a two-way table?

Back

A two-way table is a statistical table that displays the frequency distribution of variables. It allows for the comparison of two categorical variables.

How do you read a two-way table?

Back

To read a two-way table, locate the row and column that correspond to the categories of interest, and find the intersection to see 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 variable, showing the overall count for that category.

Front

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

Back

The purpose of using a two-way table is to analyze the relationship between two categorical variables and to summarize data in a clear format.

Front

How can 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 frequency and multiply by 100.

Front

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

Back

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

Front

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

Back

A joint frequency is the count of occurrences for a specific combination of categories from the two variables.

Front

How do you determine the relationship between two variables using a two-way table?

Back

You can determine the relationship by analyzing the joint frequencies and comparing the marginal totals to see if there is a pattern.

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 calculated by dividing the joint frequency by the total of the row or column.
