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 aboutx-axis title (bottom line) describing what information you test.Y-axis title (vertical line) describing what information you put
3. Title Y-AXISX- AXIS
4. X-axis (horizontal, bottom line)Your INDEPENDENT VARIABLES go along your x-axis.List each independent variable along the bottomDon’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. What is a Variable????Variables: are factors we can control, measure, or manipulate in an experimentTypes of Variables:Independent Variable:*one we manipulate and can changeEX. Colors, Days, Months, CitiesDependent Variable:*the one that we measure or observeEX. Temperature, # of shark attacksControl Variable:*the one that DOES not changeEX. Time we take temp, what tool we use, kind of flower pots
9. Independent VariableDependentVariablePossible Control Variables:*where you get data*when you take data
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 Graphs3 major types of Graphs:Bar GraphLine Graphs3. Circle GraphsBar Graphs 1. Categorical data 2. Vertical and horizontal bars3. Show amounts of each categoryLine GraphsMost common in science*Shows change over timeShows how one variable changes in response to anotherShows trends of dataCircle GraphsCategorical dataShows relationship of part to the wholeMust have data for all categoriesAlso called a pie chart
