Question

Find median from the following data: 8,6,10,12,14,18,16 for class 7 students

Answer 1

Answer:

first step is to arrange the data in either ascending order or descending order.

6, 8, 10, 12, 14, 16, 18

now count the number of observation or data.

if the number of data "n' is odd, then median

= (n + 1)/2th observation

if 'n' is even, then median

= 1/2 [ (n/2)th + (n/2 + 1)th ] observation

here n =>7 (odd)

therefore median =( n+1)/2 th observation

=> (7+1)/2

=> 8/2

=> 4th observation

=> 12

therefore median is 12
