A.
rectangles; areas; frequencies
B.
triangles; parameters; frequencies
C.

D.
rectangles: parameters: item size

Solution:

Explanation:Characteristics of a histogram:A histogram is a chart that plots the distribution of a numeric variables values as a series of bars.Each bar typically covers a range of numeric values called a bin or class.A bars height indicates the frequency of data points with a value within the corresponding bin.The histogram generally shows a frequency distribution.The width of the bars is same but height changes as per the frequency of a specific class. That implies area of each rectangle is directly proportional to frequency. Parts of a HistogramThe title: The title describes the information included in the histogram.X-axis: The X-axis are intervals that show the scale of values under which the measurements fall.Y-axis: The Y-axis shows the number of times that the values occurred within the intervals set by the X-axis.The bars: The height of the bar shows the number of times that the values occurred within the interval, while the width of the bar shows the interval that is covered. For a histogram with equal bins, the width should be the same across all bars.An example of graphical presentation of a histogram is given below,Therefore, it is clear that Histogram is associated with Continuous frequency distribution.
