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 of a category in a two-way frequency table?

Back

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

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 a two-way frequency table, representing the total counts for each category.

Front

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

Back

The purpose of a two-way frequency table is to summarize and analyze the relationship between two categorical variables.

Front

How can you determine the total number of observations from a two-way frequency table?

Back

The total number of observations can be determined by summing all the frequencies in the table.

Front

What is a conditional frequency in a two-way frequency table?

Back

A conditional frequency is the frequency of a category given a specific condition, often calculated by dividing the frequency of a cell by the total of its row or column.

Front

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

Back

To interpret the data, analyze the frequencies and percentages to understand the relationship between the two variables and identify trends.

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 two-way frequency tables be used in real-life scenarios?

Back

Two-way frequency tables can be used in surveys, market research, and studies to analyze relationships between demographic factors and preferences.

Front

What is the formula for calculating the percentage of a specific group in a two-way frequency table?

Back

Percentage = (Frequency of the group / Total frequency) x 100.
