What if the class sizes are not equal?

[@EnjoyMath]

One way could be to club class intervals in such a way that we get equal width class intervals... For example- 5-8 freq 7, 8-10 freq 3 , 10-15 freq 9 etc... We may regroup them as 5-10 freq 10, 10-15 freq 9 and so on... Then we can proceed.... Pls let me know if you have any questions...

Why did you begin finding frequency from bottom in more than question 5:13

[@EnjoyMath]

In this question, we have more than type frequency. That is, 39 students have got marks ≥ 0....but can we tell out of these 39 students how many got marks ≥ 15? How many got marks ≥ 30? No, we really cannot tell accurately at all .....but just look at the bottom most row .....marks ≥ 90 , number of students is 3...cannot we not say with 100% surety that there are 3 students who got marks ≥ 90? Definitely we can, because there is no other row after the ≥ 90 row....so surely those 3 students only have got marks ≥ 90 and hence our last row frequency becomes 3 and we can then easily find other frequencies....that is why we start from bottom most row and not top most row in case of more than frequency... Pls let me know if you have any questions.....

Maam in more than one we can do from top aswell like if it is more than or equal to 0 we know there are 39 and we know in more than or equal to 15 there are 37 That means between 0-15 there are 2 please tell if im correct)

[@EnjoyMath]

Yes, you are right!! It can be done the way you have explained!! Great going 👍👍👍 just take care while subtracting....👍👍👍
