Question

what is the median of 2,4,8,12 ?

Answer 1

Answer:

When the number of elements in array is even, then, median = [(n/2)th + (n/2th +1)]/2

Here, n = no. of elements = 4

=> (n/2) th= 2nd element = 4

=> (n/2 +1) th = 3rd element = 8

Thus, median = (4+8)/2

=> median = 12/2

=> median = 6
