Question

Find median of observation 10,12,14,16,18,20

Answer 1

Arranged data=10,12,14,16,18,20
Total number of observations =6
Median=(3rd obs+4th obs)/2=(14+16)/2=15

Answer 2

Given,

The data range of observation is = 10,12,14,16,18,20

To find,

The median of the given observation data.

Solution,

We can easily solve this mathematical problem by using the following mathematical process.

First of all, we need to arrange the data into ascending numerical values. But, in this case the given data is already arranged in ascending order.

Now, here the number of terms (n) is even (6 terms).

So, the formula which we will use to calculate the median is.

= [(n/2)th term + (n/2 +1)th term] ÷ 2

= [(6/2)th term + (6/2 +1)th term] ÷ 2

= (3rd term + 4th term)÷2

= (14+16)/2

= 30/2

= 15

Hence, the value of the median is 15
