Question

The time taken by 12 students in minutes to get ready for school is given below. Find
the median of the observations: 23, 34, 45, 43, 27, 37, 48, 53, 38, 49, 26, 40.

Answer 1

Step-by-step explanation:

First let's arrange the observations in Ascending order:

23,26,27,34,37,38,40,43,45,48,49,53

No. of Observations (n) = 12

If n is even then the median is average observation of n/2th and n/2 +1 th observation

The average of 6th and 7th observation.

=> Average of 37 and 38

$\frac{37 + 38}{2}$

=>37.5
