1. Types of Graphs PIE Graph LINE Graph BAR Graph PICTURE Graph

2. Pie Graph • Use for percentages • Should total to 100% or 360 degrees

3. Line Graph • Use with data that changes continuously

4. Bar Graph • Make comparisons between different variables very easy to see • Clearly show trends in data, meaning that they show how one variable is affected as the other rises or falls

5. Picture Graph • Shows the same type of information as a bar graph

6. Important things that MUST be on a graph • X-axis and Y-axis • Title and Sub titles on X-axis & Y-axis • Units and Numbering on X-axis & Y-axis • Legend and Key

7. X-axis and Y-Axis • X-axis is the Independent Variable • on the horizontal line • chosen by the experimenter • Stays constant, controlled • Example – Time • Y-axis is the Dependent Variable • on the vertical line • variable that CHANGES and is measured • Example – Weight (grams) or Height (cm)

8. Title and Subtitles of Graph • Titling your graph allows other people to read your graph and understand what the graph is all about • Example- “Student’s Favorite Juices” • Subtitles identify the variables being measured • Example – Juices • Example – Number of Students

9. Units and Numbering • Numbers and units on the axis must be in even increments and evenly spaced • Every line does not need to be numbered • You must stay consistent and use all of the graphing area • Numbering Example – 2,4,6,8 • Units Example – Red, Orange

10. Legend or Key • If making a multiple line graph you MUST have one • Not always necessary
