1. Collect and Analyze Data (GRAPHING)

2. What should be on every graph?
THREE TITLES!
overall title at the top of your graph describing what your graph is about
x-axis title (bottom line) describing what information you test.
Y-axis title (vertical line) describing what information you put

3. Title
Y-AXIS
X- AXIS

4. X-axis (horizontal, bottom line)
Your INDEPENDENT VARIABLES go along your x-axis.
List each independent variable along the bottom
Don’t forget to put a title along the x-axis after you have listed your independent variables

5. Independent variable

6. Y-axis (vertical line)
Your DEPENDENT VARIABLE goes along the vertical y-axis.
You must look at your data to come up with an appropriate scale.
The scale is what you count up by along the y-axis.
Example: count up by 1’s, count up by 2’s, count up by 10’s, etc.
Always start with zero in the bottom corner.

7. Dependent variable

8. Variables: are factors we can control, measure, or manipulate in an experiment Types of Variables:
What is a Variable????
Independent Variable:
*one we manipulate and can change
EX. Colors, Days, Months, Cities
Dependent
Variable:
*the one that we measure or observe
EX. Temperature, # of shark attacks
Control
*the one that DOES not change
EX. Time we take temp, what tool we use, kind of flower pots

9. Dependent
Variable
Possible Control Variables:
*where you get data
*when you take data
Independent Variable

10. Bar graph & Line graph
You will make a bar graph if you are comparing 2 or more things.
You will make a line graph if you are tracking something changing over a period of time.

15. Types of Graphs Bar Graphs Circle Graphs 3 major types of Graphs:
Line Graphs
3. Circle Graphs
Bar Graphs
1. Categorical data
2. Vertical and horizontal bars
3. Show amounts of each category
Most common in science*
Shows change over time
Shows how one variable changes in response to another
Shows trends of data
Circle Graphs
Categorical data
Shows relationship of part to the whole
Must have data for all categories
Also called a pie chart
