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 $a\le x\le b$ then the boundaries are x= a and x= b.
