Question

The following series show marks in Economics of 11 students of class XI.
Find the median marks:
Marks : 17, 32, 35, 33, 15, 21, 41, 32, 11, 10, 20​

Answer 1

Answer:

Ascending Order: 10, 11, 15, 17, 20, 21, 32, 32, 33, 35, 41

Median = Sum of  (n+1)/2th item

Median = Sum of (11+1)/2th item

Median = Sum of 12/2th item

Median = Sum of 6th item

Since the 6th item is 21.

Therefore, Median = 21
