Example 12 The heights (in cm) of 9 students of a class are as follows: 155 160 145 149 150 147 152 144 148 Find the median of this data. We arrange the data in ascending order, as follows: 144 145 147 148 149 150 152 155 160 Number of students = n = 9 (odd number) Median = ((๐‘› + 1)/2)^๐‘กโ„Ž " obs"ervation = ((9 + 1)/2)^๐‘กโ„Ž observation = (10/2)^๐‘กโ„Ž observation = 5th observation = 149 cm
