Question

Find mean and median from the following observations 10,47,3,9,17,27,4,48,12,15

Answer 1

Arranging in ascending order of magnitude we get 3, 4, 9, 10, 12, 15, 17, 27, 47, 48

Here n=10

Hence median is the average of the two middle items 12&15

•°•Median=(12+15)÷2

=27÷2

=13.5

Mean=(3+4+9+10+12+15+17+27+47+48)÷10

=192÷10

=19.2
