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 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.

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 each category, providing an overall count of observations.

Front

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

Back

To calculate the percentage, divide the frequency of a specific category by the total number of observations 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 each row or column, showing the total for each 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.

How do you determine the number of males surveyed from a two-way table?

Back

To determine the number of males surveyed, look for the total frequency in the row or column designated for males.

What is the significance of the cell values in a two-way table?

Back

The cell values represent the frequency of occurrences for the specific combination of the two categorical variables.

How can you use a two-way table to find conditional probabilities?

Back

To find conditional probabilities, divide the joint frequency of the event of interest by the marginal total of the condition.
