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..

 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. 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.
