What is the difference between joint and marginal frequencies?

Answer 1

I put the answer in a picture.

Answer 2

In a 2-Way Frequency Table, joint frequencies represent the values inside the table cells, while marginal frequencies represent the sums of the rows or columns.

In a 2-Way Frequency Table, joint frequencies represent the values inside the table cells, while marginal frequencies represent the sums of the rows or columns.

Let's say we have a frequency table with categories A and B. The joint frequency could be the number of people who fall under category A and B, while the marginal frequency would be the total number of people in category A or category B.

For example, if 20 people fall under category A and B, that would be a joint frequency, while the sum of category A or category B, like 25 people favoring category A, would be a marginal frequency.
