Question

the median of numbers 3,1,1,5,2 and 7 is?

Answer 1

Answer:

Median is 2.5

Explanation:

Median  is the value in a set which is most close to the middle of a range.

In other words, Median  is equal to  the middle value of a set of ordered data.

Given set of data is :

3,1,1,5,2,7

Firstly we will write it on order (ascending order)

1, 1, 2, 3, 5, 7

There are total 6 numbers (even)

We have a formula to find the position of median is  = $(\frac{(n+1)}{2} )^{th}  term$

Position of median  = $\frac{6+1}{2} = 3.5$

Since there is an even number of observations in this data set, there is no longer a distinct middle value.

So, we take average of 3rd and 4th term

Median  = $\frac{2+3}{2} = \frac{5}{2}  = 2.5$

So, median is 2.5
