25

0.5+1+1.5+2+2+3+3+4.5+5 median will be the middle value of our sorted array or list of numbers which is "2".

2+5+10+20+30+50+60+90 --> number of values=8/2= 4. So we will take only the middle 2 values 20 and 30 having index 4,5. take an average of them 20+30/2=50/2 -->25 ... So, he Median is 25.

4.5

50

0.5,1,1.5,2,2,3,3,4.5,5 so median is 2

10,20,30,50,52,60,90 so the median is 50

20

30 , 20, 10 , 50, 60 , 10, 90, 5, 2Now first of all we convert it into ascending order 2, 5, 10, 10, 20 , 30, 50, 60, 9020 is the median.
