Plots
A
line plot
is a graph that shows the frequency of data
on
a number line. Line plots make it easy
to identify the
mode, range,
and any outliers in a data
set.
Outliers
are data points
that
are much
larger or smaller than other
values.
To make a line
plot,
draw a number line from the least to the greatest value in the number set.
Then,
make an x above each number every time it appears in the set.

8, 9,
