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 is the purpose of a two-way table?

Back

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

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 row or column, indicating the overall count for that category.

Front

How can you find the number of people who belong to both categories in a two-way table?

Back

To find the number of people who belong to both categories, look at the cell where the corresponding row and column intersect.

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, providing the total count for that specific category.

Front

How do you calculate the percentage from a two-way table?

Back

To calculate the percentage, divide the frequency of the specific category by the total number of observations, then 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 calculated by dividing the frequency of interest by the total of the relevant row or column.

Front

How can two-way tables help in making decisions?

Back

Two-way tables help in making decisions by providing a clear visual representation of data, allowing for easy comparison and analysis of relationships between variables.

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.
