The lower BOUNDARY of each class is calculated by subtracting half of the gap VALUE 12=0.5 1 2 = 0.5 from the class lowerlimit. On the other hand, the upper boundaryof each class is calculated by ADDING half of the gap value 12=0.5 1 2 = 0.5 to the classupper limit. Simplify the lower and upperboundaries COLUMNS.
