Two-Way Frequency Tables

Front

What is a two-way frequency table?

Back

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

Front

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

Back

To determine the total frequency, sum all the frequencies in the table, including the marginal totals for each category.

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 the table, representing the total counts for each category of one variable, regardless of the other variable.

Front

How can you identify the least popular category in a two-way frequency table?

Back

To identify the least popular category, compare the frequencies of each category and find the one with the lowest frequency.

Front

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

Back

The purpose is to analyze the relationship between two categorical variables and to summarize the data in a clear and organized manner.

Front

How do you calculate the relative frequency from a two-way frequency table?

Back

Relative frequency is calculated by dividing the frequency of a specific category by the total frequency of all categories.

Front

What is the significance of the intersection of rows and columns in a two-way frequency table?

Back

The intersection of rows and columns represents the frequency count for the combination of the two categorical variables.

Front

How can you use a two-way frequency table to answer questions about subgroups?

Back

You can analyze the frequencies in specific cells of the table to answer questions about particular subgroups defined by the two categorical variables.

Front

What is an example of a categorical variable that could be used in a two-way frequency table?

Back

Examples of categorical variables include gender (male, female), car color (red, blue, white), or age group (18-25, 26-35, etc.).

Front

How do you interpret the results of a two-way frequency table?

Back

Interpretation involves analyzing the frequencies to understand the relationships and patterns between the two categorical variables.
