1. Graphing 101

2. Graphing basics Use: graph paper a ruler a pencil (be neat)
Connect data points; use a line of best fit

3. Setting up a graph DRY MIX
Dependent or Resultant variable on the Y-axis
MIX
Manipulated or Independent variable on the X-axis

4. Labeling graphs
X and Y axis - what was measured & (unit of measurement)
First data point - on, or close to the y-axis
Descriptive title - states what is on both axes
You can use “dependent variable vs. independent variable”

5. Plan intervals Space equally
Determine total range of numbers – divide by the number of lines on your axis, then round up to the closest number that is easy to work with

6. Types of graphs Line graph: graphing change over time
Bar graph: comparing data of different groups
Pie chart: comparing parts of a whole (% that add to 100)
