GRAPHING
USING DATA TO MAKE GRAPHS

WHAT IS DATA?
Data is information.
An example:
In my fifth grade class we took a pizza lovers survey.
We learned that ten kids liked pepperoni pizza best.
Nine kids liked sausage pizza best.
Seven kids liked cheese pizza best.
This information is called DATA.
WHAT IS DATA?
If a mom was planning a pizza party for the class,
she would need the pizza lovers survey DATA.
I need to order 10
pepperoni, 9 sausage
and 7 cheese pizzas.

WHAT IS DATA?
Your report card is another example of data.
Math: 88%
Reading: 94%
Science: 75%
Social Studies: 80%
Language Arts: 55%
My Language Arts
teacher may not
like me.
DATA IS EVERYWHERE.
TV
Books
Newspaper
There is way
too much data
in school!

HOW DO PEOPLE USE DATA?
We use data to make
money.
The data from
the test will
help us cure
your disease.
Data is needed to
build things.
DATA CAN BE CONFUSING.

LET’S LEARN ABOUT GRAPHS.
There are many different types of graphs.
For Example...
1. The bar graph
2. The line graph

LINE GRAPH
• A line graph is used to illustrate change over time.
• Line graphs need:
- Title
- Labeled X and Y axes
- Equal Intervals
- Data displayed by points connected into lines

DOUBLE LINE GRAPH
• A double line graph is used to compare two groups of related data over time.
• Double line graphs need:
- Title
- Labeled X and Y axes
- Equal Intervals
- Data displayed by points connected into lines
- Key

SCATTER PLOT
• Shows how closely two sets of data are related
• The closer the sets are related, the closer the points come to forming a straight line.
• Scatter Plots include:
- title
- labeled axes
- equal intervals
- corresponding numbers plotted as ordered pairs

HOW TO CONSTRUCT A LINE GRAPH ON PAPER
How to Construct a Line Graph on Paper
Step What To Do How To Do It
1Identify the
variables
a. Independent variable – (controlled by the
experimenter)
Goes on the x-axis (horizontal)
Should be on the left side of a data table
a. Dependent variable – ( changes with the
independent variable)
Goes on the y-axis (vertical)
Should be on the right side of a data table
2Determine the
variable range
a. Subtract the lowest data value from the
highest data value
b. Do each variable separately

3Determine the
scale of the graph
a. Determine scale (the numerical value for
each square) that best fits the range of
each variable
b. Spread the graph to use MOST of the
available space
4Number and label
each axis
This tells what data the line on your graph
represent.

Step What To Do How To Do It
5Plot the data
points
a. Plot each data value on the graph with a
dot
b. You can put the data number by the dot, if
it does not clutter your graph
6 Draw the graph
a. Draw a curve or a line that best fits the
data points
b. Most graphs of experimental data are not
drawn as “connect-the-dots”

7 Title the graph
a. Your title should clearly tell what the graph
is about
b. If your graph has more than one set of
data, provide a “key” to identify the
different lines.
