A)A histogram shows the cumulative relative frequency distribution.
B)A histogram may be used as a graphical display of ordinal data.

Question

Quizplus · Accepted Answer

A histogram is a graphical display of numerical data where the data is divided into intervals or bins and the frequency (or relative frequency) of each interval is represented by the height of a rectangle. The horizontal axis of a histogram follows a numerical scale, and there are no gaps between the rectangles because the intervals are contiguous. Therefore, choice D is the correct statement. Choice A is incorrect because it refers to a cumulative relative frequency distribution, which is a different type of graphical display. Choice B is incorrect because histograms are typically used with continuous numerical data, not ordinal data. Choice C is incorrect because histograms are not appropriate for displaying categorical data.
