The heights (in cm) of 50 students of class are given below.
Find the median height
Draw the cumulative frequency table;
N = ∑f = 50 (even)
Median = 1/2 [value of (n/2)th term + value of (n/2 + 1)th term]
⇒ Median = 1/2 [value of 25th term + value of 26th term]
⇒ Median = 1/2 [154 + 155] = 309/2 = 154.5cm
