Graphing
Also known as the most fun you’ve ever had 

2. 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

3. 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?

4. 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!

5. Labeling.. Where do they go?
I.V.
D.V.

6. 3 types of graphs.. 1. bar graph Used for categories Example: Months
Animals
Cars
Etc..

7. 3 types of graphs continued..
2. line graph
Used to show trends or things that happen over time
Notice that
both sides
are scaled!

8. Trends
Upward trend
The data amounts plotted increases over time

9. Trends continued.. Downward Trend
The data amounts plotted decrease over time

10. 3 types of graphs continued..
3. circle graph
AKA pie chart
Used for showing parts of a total

11. 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.
