What is a 2 Way Table?

Back

A 2 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 percentage from a 2 Way Table?

Back

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

Front

What does it mean if a 2 Way Table shows a higher percentage of one category over another?

Back

It indicates that there is a greater proportion of that category within the surveyed population, suggesting a potential trend or preference.

How can you interpret the data in a 2 Way Table?

Back

By examining the frequencies and percentages, you can identify trends, compare groups, and make inferences about the relationship between the two variables.

Front

What is the difference between marginal and conditional frequencies in a 2 Way Table?

Back

Marginal frequencies are the totals for each category, while conditional frequencies are the frequencies of one variable given a specific category of the other variable.

Front

What is a joint frequency in a 2 Way Table?

Back

A joint frequency is the count of occurrences for a specific combination of categories from the two variables.

Front

How do you find the total percentage of a category in a 2 Way Table?

Back

Add the joint frequencies of that category across all rows or columns, then divide by the total number of observations and multiply by 100.
