How to set up successful graphs
in science class!
Let’s create a bar graph with
this format.

You will have a
wonderful graph if
you follow the
T.A.I.L.S. system.
It will help you set
up and label your
graph properly.

Decide on an appropriate
scale for each axis.
T – Title
Choose a scale that lets
you make the graph as
large as possible for your
paper and data.

• Scale is determined
by your highest &
lowest number.
• In this case your
scale would be from
2 – 22.

The amount of space between one
number and the next or one type of
data and the next on the graph is
the interval.
The interval is just as important as
the scale.
Choose an interval that lets you
make the graph as large as possible
for your paper and data.

• The interval is decided
by your scale.
• In this case your scale
would be from 2 – 22
and you want the scale
to fit the graph.
• A good interval would
be to go by 5’s.

When to use…
0011 0010 1010 1101 0001 0100 1011
• Bar graphs
– Used to show data that are not continuous.
– Allow us to compare data like amounts or
frequency or categories.
– Allow us to make generalizations about the
data.
– Help us see differences in data.

We can also plot the data on…

• Line Graphs
– For continuous data.
– Useful for showing trends over time.

Here’s
how
that
would
be
done.
With this type of info, a line graph does not make any sense unless

the colors are listed in order like they are below.
