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.

How do you read a two-way frequency table?

Back

To read a two-way frequency table, locate the row and column corresponding to the categories of interest, and find the intersection to see the frequency count.

Front

What does the term 'marginal frequency' mean?

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?

Back

Conditional frequency is the frequency of a specific category given another category, often found by dividing the frequency of the intersection by the total of the row or column.

Front

How do you calculate the percentage from a frequency table?

Back

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

Front

What is the purpose of using two-way frequency tables?

Back

Two-way frequency tables are used to analyze the relationship between two categorical variables and to identify patterns or trends in the data.

Front

What is the difference between a frequency and a relative frequency?

Back

Frequency is the count of occurrences of a category, while relative frequency is the proportion of the total that the category represents.

Front

How can you determine which group prefers a certain option using a two-way frequency table?

Back

By comparing the frequencies of the option across different groups, you can identify which group has the highest or lowest preference.

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 distribution.

Front

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

Back

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