- 3. Section 2.2: Practice reading a histogram (prerequisite review). A histogram is a graph that organizes quantitative data, like counts and measurements, so we can see the distribution of these data values (i.e. how they vary). The horizontal axis shows the range of values we might see in the data. The vertical axis shows the frequency, or how many times those values appear in our data set. Number of subjects (Note: The axes on graphs in statistics rarely include "break lines" when the graphs do not start at 0. Likewise, the location of 0 is sometimes offset, i.e. moved over, to help us better read the graph.) The following histogram shows the results of a study of adolescent girls in Pennsylvania.
