TWO-WAY TABLES

Front

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.

Front

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.

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 each category, providing an overall count of observations.

Front

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

Back

To calculate probability, divide the frequency of the event of interest by the total number of observations.

Front

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

Back

A marginal total is the sum of the frequencies for a single category, found in the margins of the table.

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

Back

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

Front

What is conditional probability in the context of a two-way table?

Back

Conditional probability is the probability of an event occurring given that another event has already occurred, often calculated using the relevant row or column totals.

Front

What is the difference between joint and marginal distributions?

Back

Joint distribution shows the frequency of combinations of two variables, while marginal distribution shows the frequency of each variable independently.
