30,20,10,50,60,90,5,2 , let's find out the median.
step 1. to arrange in ascending order
2,5,10,20,30,50,60,90 So the list of numbers are even.
step2: taking average of middle two number which are 20,30
avg = 20+30/2=25. hence the median is 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.
