How Do You Find CLASS LIMITS Given Only A CLASS BOUNDARIES?
no, unlike the formula for going from limits to boundaries, there is no formula for going from boundaries to limits. Boundaries are usually values that can not occur in your data, so basically you need to look at your data and determine what data value is the first one that is higher than your boundary and that becomes the lower limit for the next class. In the same way you look at the highest data value that is less than your boundary and that becomes the upper limit for the class below the boundary.
