Question
Transcribed Image Text: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. The girls
reported their daily fruit servings as a whole number.
