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.

Front

How do you calculate the total frequency in a two-way frequency table?

Back

To calculate the total frequency, sum all the frequencies in the table, both row-wise and column-wise.

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 (the last row and last column) of a two-way frequency table, representing the total counts for each category.

Front

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

Back

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

Front

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

Back

The purpose is to analyze the relationship between two categorical variables and to summarize data for easier interpretation.

Front

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

Back

Interpretation involves examining the frequencies and percentages to identify trends, relationships, or patterns between the two variables.

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 conditional percentage in a two-way frequency table?

Back

To find the conditional percentage, divide the conditional frequency by the total frequency of the condition and multiply by 100.

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

Back

By analyzing the frequencies and percentages, you can answer questions about relationships, preferences, and trends between the two variables.
