Work Step by Step
"College Experience" in an attribute of a group of students.
"Homework System" is the characteristic of the teaching methodology.
"Number of Students" is a numerical measure of a group of students. Number of students can be added or subtracted. We can count the number of students: 0, 1, 2, 3, ...
"Average Age" is a numerical measure of a group of students. Average age can be added or subtracted. There are infinite numbers we can use to measure average age. In other words, between two possible numbers, there are an infinite number of other possible numbers we can use to measure average age.
"Average Exam Score" is a numerical measure of a group of students. Average age can be added or subtracted. There are infinite numbers we can use to measure average exam score. In other words, between two possible numbers, there are an infinite number of other possible numbers we can use to measure average exam score.
