help with class boundaries and inequalities

Hi;

How do I determine class boundaries when the class intervals are inequalities?

Thank you.

It would help to see an example of what you are talking about but I think that if you have inequalities such as a< x< b or then the boundaries are x= a and x= b.

class intervals

20 less than equal to w less than 25
25 less than equal to w less than 30

So the boundaries are?

Why x=a and x=b?

class boundaries 20,25 and 25,30

Are my class boundaries above right?

Thanks.

Yes.

Thank you but I thought they were class limits?

So are the class limits 20 and 24.9

25 and 29.5?

What is are class boundaries and class limits in statistics and how can I find them?
