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 find the total number of surveyed individuals in a two-way frequency table?

Back

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

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 (rows and columns) of a two-way frequency table, representing the total counts for each category.

Front

How can you determine the percentage of a specific group in a two-way frequency table?

Back

To determine the percentage of a specific group, divide the frequency of that group by the total number of surveyed individuals 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 organize and summarize data to identify patterns, relationships, and trends between two categorical variables.

Front

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

Back

To interpret the data, analyze the frequencies and percentages to understand the relationship between the two variables and draw conclusions.

Front

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

Back

A conditional frequency is the frequency of a specific category of one variable given a particular category of another variable.

Front

How can you use a two-way frequency table to answer application-based questions?

Back

You can use a two-way frequency table to answer application-based questions by analyzing the frequencies and calculating percentages to draw conclusions about the data.

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 from both variables, while marginal frequency refers to the total counts for each category.

Front

How do you calculate the joint frequency for two categories in a two-way frequency table?

Back

To calculate the joint frequency, locate the intersection of the row and column corresponding to the two categories in the table.
