What was the median grade point average of the 3,000 students in 1950?
(A) 3.7
(B) 3.3
(C) 3.0
(D) 2.7
(E) 2.3
Here,
Total no. of students = 3000
so the 1500 or 1501 student will be the median range.
Now,
Students in 4.0 grade = 150
Students in 3.7 grade = 225 and
total Students = 150 + 225 = 375
Students in 3.3 grade = 300 and
total Students = 300 + 375 = 675
Students in 3.0 grade = 450 and
total Students = 675 + 450 = 1125
Students in 2.7 grade = 475 and
total Students = 475 + 1125 = 1600
Thus in the grade of 2.7, the median students falls under this range
so, the median grade range =
2.7
