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 lower limit. On the other hand, the upper boundary of each class is calculated by adding half of the gap value 12=0.5 1 2 = 0.5 to the class upper limit. Simplify the lower and upper boundaries columns.
