Marginal frequency:

The number in the end column or row - "Total".

Joint frequency:

The proportion of the frequency in a particular category and the total variety of information values.

Basically, the values that aren"t in the last row or column - "Total".

The number of students that are in 9th grade and play two or more sports is a joint frequency.

This is just asking for the students in 9th grade who play 2 or even more sporting activities.

The number of students that are in the 11th grade is a marginal frequency.

This is asking for the full number of students in 11th grade.

The percent of the student body that plays one sport is a marginal loved one frequency".

This is asking for the full variety of students that play 1 sport.

The percentage of the student body that are in 12th grade and also carry out not play a sport is a joint family member frequency.

This is just asking for the students in 12th grade and also don"t play sporting activities.
