Question

find the median 20,21,21,6,15,18,45,9,6,26,15,

Answer 1

Answer:

16

Step-by-step explanation:

The value of the middle-most observation is called the median of the data. First arrange the given numbers in ascending order, 6, 8, 9, 13, 15, 16, 18, 20, 21, 22, 25 Here n = 11, which is odd. Where, n is the number of the given number. ∴median = value of ½ (n + 1)th observation. = ½ (11 + 1) = ½ (12) = 12/2 = 6 Then, value of 6th term = 16 Hence, the median is 16.Read more on Sarthaks.com - https://www.sarthaks.com/755154/find-the-median-of-21-15-6-25-18-13-20-9-16-8-22
