What does a histogram show?
A)A histogram is a graph in which values of observations are plotted on the horizontal axis, and the frequency with which each value occurs in the data set is plotted on the vertical axis.
B)A histogram is a graph in which values of observations are plotted on the horizontal axis, and their density is plotted on the vertical axis.
C)A histogram is a graph in which levels of the independent variable are plotted on the horizontal axis, and the mean of observations is plotted on the vertical axis.
D)A histogram is a graph in which values of one variable are plotted against values of a different variable.

Question

Quizplus · Accepted Answer

A histogram shows the frequency distribution of a single variable, where the values of observations are plotted on the horizontal axis and the frequency of these values is plotted on the vertical axis. It is a graphical representation of a frequency distribution. Choice B is incorrect because a histogram does not show density but the frequency of values. Choice C is incorrect because a histogram does not plot the mean of observations. Choice D is incorrect because a histogram is a graph of a single variable, not two different variables.
