Hi, I think that there is a problem at the practice question. It says 2 + 12+28+40 = 82 but when I counted it equals to 100
Use a calculator next time
We will add1 in total frequency and divide by 2 in all tables?right?
Hi, yes, that is how you calculate the median. 😊
Hi, why do we add the one? Will it be the same for all questions? Like for example the frequency in 20. Do I still add 1 and divide by 2?
Hi Sreedadha,Yes we always add 1.This is how we find the middle number.For example:1 2 3Which is the middle position here?It’s not half of three (1.5), it’s (3+1)/2=2The middle position is the 2. That’s why we add the one. 😊

Hi Sreedadha,
Yes we always add 1.
This is how we find the middle number.
For example:
1 2 3
Which is the middle position here?
It’s not half of three (1.5), it’s (3+1)/2=2
The middle position is the 2.
That’s why we add the one. 😊
