Question

Quizplus · Accepted Answer

The boundaries of the class 11-18 are 10.5 and 18.5 because in statistics, to avoid ambiguity in class limits, the real limits or boundaries of each class are considered to be halfway between the upper limit of one class and the lower limit of the next. This means for a class of 11-18, the lower boundary is 10.5 (11 - 0.5) and the upper boundary is 18.5 (18 + 0.5).
