Two-way frequency tables

Front

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 calculate the percentage of a category in a two-way frequency table?

Back

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

Front

What does the term 'marginal frequency' refer to in a two-way frequency table?

Back

Marginal frequency refers to the totals found in the margins of a two-way frequency table, representing the total counts for each category.

Front

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

Back

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

Front

How can you identify the most common category in a two-way frequency table?

Back

The most common category can be identified by looking for the highest frequency count in the table.

Front

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

Back

Conditional frequency is the frequency of a category given a specific condition or category of the other variable.

Front

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

Back

The total number of observations can be found by summing all the frequencies in the table.

Front

What is the difference between joint frequency and marginal frequency?

Back

Joint frequency refers to the frequency of occurrences for a specific combination of categories, while marginal frequency refers to the total counts for each category.

Front

How can two-way frequency tables help in making predictions?

Back

Two-way frequency tables can help in making predictions by showing patterns and relationships between variables, which can be used to infer future outcomes.

Front

What is the significance of the total row and column in a two-way frequency table?

Back

The total row and column provide the marginal frequencies, which summarize the overall counts for each category.
