Graphing
Also known as the most fun you’ve
ever had
5 steps to making a
complete graph..
1. Title your graph
2. Determine your I.V. and D.V.
This is important when labeling the graph
3. Draw axis
Scale the graph and label X and Y axis
4. Plot data
5. Make a conclusion statement
Scaling..
Scales are number patterns that you will use
when labeling your graph
Examples:
2, 4, 6, 8, 10..
1, 2 ,3 ,4 ,5 ,6..
5, 10, 15, 20..
3,6. 9,12,15,18..
10, 20, 30, 40..
See the scale?
Labeling..
You must label your graph in order for it to be
properly read or understood.
Without proper labeling, it would just be bars or
lines on a page.
The I.V. is always labeled on the X axis
The D.V. is always located on the Y axis!
Labeling.. Where do they
go?
I.V.
D.V.
3 types of graphs..
1. bar graph
Used for categories
Example:
Months
Animals
Cars
Etc..
3 types of graphs
continued..
2. line graph
Used to show trends or things that happen over time
Notice that
both sides
are scaled!
Trends
Upward trend
The data amounts plotted increases over
time
Trends continued..
Downward Trend
The data amounts plotted decrease over
time
3 types of graphs

3. circle graph
AKA pie chart
Used for showing parts of a total
What kind of graph would
you use here?
A researcher is trying to show the percentage
of pine trees in a forest compared to 3 other
species.
A census worker is trying to explain growth
trends in the human population over the next
50 years.
A game warden is explaining deer population
numbers to hunters from Mississippi, Alabama,
Louisiana, and Arkansas.
