What does the quartile button do?
This function divides the entire group of students into four groups, each consisting of 25% of the total number of students in the class. The size of each quartile will depend on the total number of students being evaluated. Students are then assigned to one of the four Quartiles based on their score on the group of cases. This allows the instructor to see whether most student scores are concentrated in a certain range, or if they are distributed over a large scoring range. Example: In a class with a total of 16 students, each of the four quartiles would contain four student scores. One quartile would contain all students who scored in the top 25% of their class. The next quartile would contain the four student scores that fall next in the scoring hierarchy, and so on. When an instructor uses the Quartile function, the student can also receive a Quartile ranking, informing him/her of how their score ranked in relation to the other students in the group.
