Thread: help with class boundaries and inequalities

1. help with class boundaries and inequalities

Hi;

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

Thank you.

2. Re: help with class boundaries and inequalities

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.

class intervals

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

4. Re: help with class boundaries and inequalities

So the boundaries are?

5. Re: help with class boundaries and inequalities

Why x=a and x=b?

class boundaries 20,25 and 25,30

6. Re: help with class boundaries and inequalities

8. Re: help with class boundaries and inequalities
