How do you read a two-way table?

Back

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

Front

What does the total in a two-way table represent?

Back

The total in a two-way table represents the sum of all frequencies for a particular variable, showing the overall count for that category.

How can you find the number of respondents who prefer one option over another in a two-way table?

Back

You can find the number of respondents who prefer one option by looking at the corresponding row or column in the two-way table.

What is the purpose of using a two-way table in statistics?

Back

The purpose of using a two-way table is to summarize and analyze the relationship between two categorical variables, making it easier to interpret data.

Front

What is a marginal total in a two-way table?

Back

A marginal total is the sum of the frequencies in a row or column, showing the total count for that category.

Front

How do you calculate the percentage of a category in a two-way table?

Back

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

Front

What is the difference between joint frequency and marginal frequency?

Back

Joint frequency refers to the count of occurrences for a specific combination of categories, while marginal frequency refers to the total count for a single category.

Front

How can you determine if there is a relationship between two variables using a two-way table?

Back

You can determine if there is a relationship by analyzing the joint frequencies and comparing them to the marginal frequencies.

Front

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

Back

A conditional frequency is the frequency of a category given a specific condition, often found by dividing the joint frequency by the total of the relevant row or column.
