Question

Find the median of the data :
30,25, 32, 23, 42,36,40,33, 21, 43.​

Answer 1

Answer:

First, We arrange it

21 , 23 , 25 , 30 , 32 , 33 ,36 , 40 , 42 , 46

Total observation is 10 i. e, even number

Median = 1/2 × ( n /2 ) + ( n/2 + 1 )

= 1/2 × (10/2 ) + (10/2 + 1)

= 1/2 ( 5 th observation + 6 that observation)

= 1/2 ( 32 + 33 ) = 1/2 × 65 = 32.5

therefore, the median is 32.5
