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. It allows for the comparison of the relationship between the two variables.

How do you find the total number of observations in a two-way table?

Back

To find the total number of observations, sum all the frequencies in the table.

Front

What does each cell in a two-way table represent?

Back

Each cell in a two-way table represents the frequency count of occurrences for the combination of the two categorical variables.

Front

How can you determine the marginal totals in a two-way table?

Back

Marginal totals are found by summing the frequencies across each row and each column.

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 do you calculate the percentage of a specific category in a two-way table?

Back

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

Front

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

Back

A conditional frequency is the frequency of a specific category given a condition on another variable, often found by dividing the cell frequency by the total of the row or column.

Front

How can you identify trends in a two-way table?

Back

Trends can be identified by comparing the frequencies across rows and columns to see how one variable affects the other.

Front

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 counts for each category, regardless of the other variable.

Front

How do you interpret the data in a two-way table?

Back

Interpreting data involves analyzing the frequencies, identifying patterns, and drawing conclusions about the relationship between the two variables.
