a. The wealth of the parents of students attending your school
b. The values that a group of fourth-grade students would give for the length of a segment that they measured with a ruler
c. The SAT or ACT examination scores in mathematics for students who were in your high school graduation class
d. The weights of all incoming freshman students at your school
