A less-than ogive for 100 students' marks is given by the points (20,10),(40,30),(60,55),(80,85),(100,100). Using graphical estimation, between which two consecutive points does the median (N/2 = 50) lie, and in which class?

Question

Accepted Answer

Between (40,30) and (60,55); class 40-60. N/2 = 50 lies between cf = 30 (at 40) and cf = 55 (at 60), so the median falls in the class 40-60.
