6. A bar chart may be displayed horizontally. 11. A polygon connects a series of neighboring points where each point represents the midpoint of a
particular class and its associated frequency or relative frequency.

7. To approximate the width of a class in the creation of a bar chart, we may use this formula:
12. An ogive is a graph that plots the cumulative frequency (or the cumulative relative frequency) of
each class above the lower limit of the corresponding class.
True False
13. A stem-and-leaf diagram is useful in that it gives an overall picture of where quantitative data are
True False
centered and how the data are dispersed from the center.
8. For quantitative data, a relative frequency distribution identifies the proportion of observations that
True False
fall into each class.
14. A scatterplot is a graphical tool that helps determine whether or not two quantitative variables are
True False
related.
9. For quantitative data, a cumulative relative frequency distribution records the proportion (fraction)
True False
of values that fall below the upper limit of each class.
15. When constructing a scatterplot for two quantitative variables, we usually refer to one variable as
True False
x and another one as y. Typically, we graph x on the vertical axis and y on the horizontal axis.
10. A histogram is a series of rectangles where the width and height of each rectangle represent the
True False
frequency (or relative frequency) and the width of the class, respectively.

pie.
