Question

Quizplus · Accepted Answer

Class boundaries are used in continuous data to avoid gaps between intervals, and they differ slightly from class limits to ensure each data point belongs to one and only one interval. Class limits define the actual range of data values that can fall within an interval, whereas class boundaries adjust these limits slightly to cover the entire data range without overlap or gaps.
