Question

Find the median from this set of numbers1,1,2,2,5,5,8,9,10,11

Answer 1

To find the median of a set of numbers, first we need to put the numbers in the crescent order (in our case, the set of numbers is already in the crescent order).

Then, we need to find the mid term of the set (the number in the middle of the set of numbers).

If we have 'n' numbers in the set, and 'n' is an odd number, the mid term is the (n+1)/2 term.

If 'n' is an even number, the median will be the average of the n/2 term and the (n+2)/2 term.

In this case, our set has 10 numbers, so as we have an even amount of numbers, the median will be the average of the 5th and the 6th numbers.

The 5th number is the number 5, and the 6th number is also the number 5, so we have:

`\text{median}=(5+5)/(2)=(10)/(2)=5`

So the median of this set of numbers is 5.
