Front

What is a two-way table?

Back

A two-way table is a statistical table that displays the frequency distribution of two categorical variables, allowing for the analysis of the relationship between them.

How do you calculate the total in a two-way table?

Back

To calculate the total in a two-way table, sum the frequencies in each row and each column.

Front

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

Back

Marginal frequency refers to the totals found in the margins (last row and last column) of a two-way table, representing the total counts for each category.

Front

What is the purpose of a two-way table?

Back

The purpose of a two-way table is to organize data to show the relationship between two categorical variables and to facilitate comparison.

Front

How do you find the conditional frequency in a two-way table?

Back

Conditional frequency is found by dividing the frequency of a specific category by the total frequency of the row or column it belongs to.

Front

What is the formula for calculating probability from a two-way table?

Back

Probability = (Frequency of the event) / (Total number of observations).

Front

How can you determine the percentage of a specific outcome in a two-way table?

Back

To determine the percentage, divide the frequency of the specific outcome by the total frequency and multiply by 100.

Front

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

Back

Joint frequency refers to the count of occurrences for a specific combination of categories from the two variables.

Front

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

Back

Interpreting data in a two-way table involves analyzing the joint and marginal frequencies to understand the relationship between the two variables.

Front

What is the significance of the total row and column in a two-way table?

Back

The total row and column provide a summary of the overall counts for each category, helping to understand the distribution of data.
