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 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 the table, representing the total counts for each category.

Front

What is 'joint frequency' in a two-way frequency table?

Back

Joint frequency is the count of occurrences for a specific combination of categories in the two-way table.

Front

How can you find the percentage of a subgroup in a two-way frequency table?

Back

To find the percentage of a subgroup, divide the joint frequency of that subgroup by the total frequency of the relevant category and multiply by 100.

Front

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

Back

The purpose is to summarize and analyze the relationship between two categorical variables, making it easier to identify patterns and trends.

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, often found by dividing the joint frequency by the total of the condition category.

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 identify any trends.

Front

What is the difference between relative frequency and absolute frequency?

Back

Absolute frequency is the count of occurrences, while relative frequency is the proportion of occurrences relative to the total.

Front

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

Back

They can help identify trends and relationships that can be used to make informed predictions about future occurrences.
