Question
The following dataset represents the examination scores
achieved by 10 students: 36, 91, 80, 77, 64, 80, 45, 56, 41, 96 Find the median of the marks received by the 10 students.Solution
Arranging the data in ascending order: 36, 41, 45, 56, 64, 77, 80, 80, 91, 96 Total number of observations = 10 So, median of the data = average of (10/2)th observation + {(10/2) + 1} observation = (64 + 77) ÷ 2 = 70.5
