Median for given observations is 1.5

Explanation:

We have two formulas to find median

Case 1: when number of observations is even we find median as below

taking average of $\frac{n}{2}term$ and $\frac{n+1}{2}term$

Case 2: when number of observations is odd we find the $\frac{n+1}{2}term$

Here we have total 10 number of observations so this falls in the category of Case 1 which is for even terms.

we have to take the average of $\frac{n}{2}$ term and $\frac{n+1}{2}$ term

Here n = 10 so substituting the value of n = 10 in the formula we will get

$\frac{10}{2}=5$

$\frac{10}{2}+1=6$

So, taking the average of $5^{th} and 6^{th}$ term means taking numbers at $5^{th} and 6^{th}$ position that is 1 and 2

It will gives $\frac{1+2}{2}$ =1.5
