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 calculate the relative frequency in 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 does it mean if a two-way frequency table shows a high percentage of one category over another?

Back

A high percentage indicates a stronger association or preference for that category compared to others.

Front

What is the formula to find the percentage of a subgroup in a two-way frequency table?

Back

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

Front

How can two-way frequency tables be used in real-life applications?

Back

They can be used in surveys, market research, and studies to analyze relationships between two variables, such as age and product preference.

Front

What is the significance of marginal totals in a two-way frequency table?

Back

Marginal totals provide the sum of frequencies for each category, helping to understand the overall distribution of data.

Front

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

Back

Interpretation involves analyzing the frequencies and percentages to identify trends, relationships, and patterns between the two variables.

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 frequency for a single category.

Front

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

Back

Calculating percentages helps to compare the relative sizes of different categories and understand their significance in the data.

Front

How do you find the percentage of a specific category given the total?

Back

Divide the frequency of the specific category by the total frequency and multiply by 100.
