2-way tables

Front

What is a 2-way table?

Back

A 2-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 2-way table?

Back

To read a 2-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 does the term 'marginal frequency' mean in a 2-way table?

Back

Marginal frequency refers to the totals found in the margins (last row and last column) of a 2-way table, showing the total counts for each category.

Front

What is a conditional frequency in a 2-way table?

Back

Conditional frequency is the frequency of a specific category given another category, often expressed as a proportion of the total for that row or column.

Front

How can you determine the relationship between two variables using a 2-way table?

Back

By analyzing the frequencies and conditional frequencies, you can identify patterns or associations between the two variables.

Front

What is the purpose of using a 2-way table in statistics?

Back

The purpose is to summarize and analyze the relationship between two categorical variables, making it easier to interpret data.

Front

What is an example of a categorical variable?

Back

Examples of categorical variables include gender, favorite color, or type of movie.

Front

How do you calculate the total number of observations in a 2-way table?

Back

Add all the frequencies in the table to find the total number of observations.

Front

What is the difference between a 2-way table and a frequency distribution?

Back

A frequency distribution shows the frequency of one variable, while a 2-way table shows the relationship between two variables.

Front

What does it mean if two variables are independent in a 2-way table?

Back

If two variables are independent, the conditional frequencies of one variable do not change based on the other variable.
