50% of the students in a school were boys. 20% of the boys and 2/3 as many girls as boys took part in a Math quiz. If a total of 80 boys and girls took part in the Math quiz, what is the difference between the number of boys and girls who did not take part in the quiz?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered.

A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
