A less-than ogive of 90 students' scores is shown. The dashed construction line is drawn from N/2 on the y-axis to find the median. Read the median score from the graph.

Question

Accepted Answer

50. N/2 = 90/2 = 45. From cf = 45 we go horizontally to the curve, then down to x = 50, so the median score is 50.
