9. A histogram is a series of rectangles where the width and height of each rectangle represent the frequency (or relative frequency) and the width of the class, respectively. FALSE A histogram is a series of rectangles the width and height of each rectangle represent the class width and frequency (or relative frequency) of the class, respectively.

An ogive is a graph that plots the cumulative frequency (or the cumulative relative frequency) of each class above the lower limit of the corresponding class. FALSE An ogive is a graph that plots the cumulative frequency (or the cumulative relative frequency) of each class against the upper limit of the corresponding class.
