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 combinations of two categorical variables, allowing for the analysis of the relationship between them.

Front

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

Back

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

Front

What does the term 'marginal frequency' mean 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 a conditional frequency in a two-way frequency table?

Back

Conditional frequency is the frequency of a specific category given a condition, often calculated by dividing the frequency of the category by the total of the row or column it belongs to.

Front

How can you identify trends in a two-way frequency table?

Back

Trends can be identified by comparing the frequencies and percentages across different categories to see how they relate to each other.

Front

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

Back

The purpose is to summarize and analyze the relationship between two categorical variables, making it easier to interpret data.

Front

What is the difference between relative frequency and absolute frequency?

Back

Absolute frequency is the count of occurrences of a category, while relative frequency is the proportion of that count compared to the total.

Front

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

Back

Interpretation involves analyzing the frequencies and percentages to understand the relationship between the two variables and draw conclusions.

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 overall counts for each category, which are essential for calculating percentages and understanding the data.
