What is a two-way frequency table?

Back

A two-way frequency table is a statistical tool that displays the frequency of different outcomes in two categorical variables, allowing for the analysis of the relationship between them.

How do you read a two-way frequency table?

Back

To read a two-way frequency table, locate the row and column that correspond to the categories of interest, and find the intersection to see the frequency count.

Front

What does the term 'relative frequency' mean?

Back

Relative frequency is the ratio of the frequency of a particular category to the total number of observations, often expressed as a percentage.

Front

How do you calculate the percentage from a frequency?

Back

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

Front

What is the purpose of a two-way frequency table?

Back

The purpose of a two-way frequency table is to summarize data and show the relationship between two categorical variables.

Front

What is the difference between frequency and relative frequency?

Back

Frequency is the count of occurrences of a category, while relative frequency is the frequency expressed as a fraction of the total.

Front

How can you find the total frequency in a two-way table?

Back

To find the total frequency, sum all the frequencies in the table.

Front

What does a high relative frequency indicate?

Back

A high relative frequency indicates that a particular category occurs frequently compared to the total number of observations.

Front

How do you determine the percentage of a subgroup in a two-way table?

Back

To determine the percentage of a subgroup, divide the frequency of the subgroup by the total frequency and multiply by 100.

What is an example of a two-way frequency table?

Back

An example of a two-way frequency table could show the number of students who like different types of food (pizza, burgers) by gender (male, female).
