Find the Median for the following set of data 11 22 5 7 30

Find the Median for the following set of data: 11 , 22 , 5, 7, 30 5 11 6 15 QUESTION 5 Find the Median for the following set of data: 25 , 20, 8 ,10, 28 , 16 ,22, 15 22 19 18 25 QUESTION 6 Calculate Weighted Mean for the following Data: 29 28 26

Solution

Arrange the set of data in an ascending order:

5,7,11,22,30

Thus, the median value is 11.

Arrange the set of data in an ascending order:

8,10,15,16,20,22,25,28

The median value is the (16+20)/2=18

The weighted mean is:

(20*2+25*4+32*4+40*2)/(20+25+32+40)

=348/117

=2.97
