Question

if 20 is removed from the data 20,24,25,26,27,28,29,30 then the median is increased by?

Answer 1

if 20 is removed then answer will be 27

Answer 2

Answer:

We observe that median is increased by 0.5

Step-by-step explanation:

As per the data given in the question,

We know,

Median is the middle term that is in the seried when we arrange it in ascending order.

So, after arranging,

20,24,25,26,27,28,29,30

Since, number of terms is 8. So,

median is avg. of 4th and 5th term = $\frac{26+27}{2} =26.5$

Now, after removing 20.

Series will be 24,25,26,27,28,29,30

New mediuan will be the 4th term =27

Hence,

We observe that median is increased by 0.5
