Question

Find the median of the following set of observation. 11,11,13,15,16,17,18,18,19,20.

Answer 1

Answer:

16.5

Step-by-step explanation:

N=10 (EVEN)

MEDIAN FORMULA=N/2 AND N/2+1

THEREFORE   N/2 = 10/2 = 5th observation

                       N/2+1 = 10/2+1 = 6th observation

MEDIAN = 5th observation + 6th observation/2

              = 16+17/2

              = 33/2

              = 16.5
