Dotplot
Step 1
:
Label your axis and title your graph.
Draw a horizontal line and label it with
the variable.
Step 2
:
Scale the axis based on the values of
the variable.
Step 3
:
Mark a dot above the number on the
horizontal axis corresponding to each
data value.
Distribution
To describe the overall pattern of a distribution:
Step 1:
Give the center and the spread.
(Divide observations in half for now.)
Step 2
:
See if the distribution has a simple shape
that you can describe in a few words.
( State the smallest and largest data.)
