1. GRAPHING
A “PICTURE” OF THE RELATIONSHIP BETWEEN THE INDEPENDENT AND DEPENDENT VARIABLES

2. VARIABLES
X – AXIS: INDEPENDENT
Y – AXIS: DEPENDENT

3. TYPES OF GRAPHS
BAR GRAPH

4. HISTOGRAM

5. PIE GRAPH/CHART

6. PICTOGRAM

7. SCATTERPLOT

8. LINE GRAPH

9. FOR A LINE GRAPH
DO A SCATTERPLOT FIRST
DRAW A BEST FIT LINE OR CURVE
LOOK AT THE DATA AND
DECIDE WHETHER THE DATA
OVERALL IS IN A LINE OR A
CURVE
DON’T PLAY CONNECT THE DOTS

10. LINE GRAPH RELATIONSHIPS
LINEAR (DIRECT)
THE INDEPENDENT VARIABLE DOES THE SAME AS THE DEPENDENT VARIABLE
EX: IF INDEPENDENT VARIABLE INCREASES BY 2 UNITS, SO WILL THE DEPENDENT VARIABLE

11. LINEAR

12. INVERSE (INDIRECT)
THE INDEPENDENT VARIABLE DOES THE OPPOSITE OF THE DEPENDENT VARIABLE
EX: AS THE INDEPENDENT VARIABLE INCREASES, THE DEPENDENT VARIABLE DECREASES

13. INVERSE

14. COMPONENTS NEEDED FOR A GRAPH
AXIS SCALES (NUMBERS) EVENLY SPACED, BE SURE ALL DATA POINTS CAN FIT ON THE GRAPH
AXIS LABELS (QUANTITY AND UNIT)
EX: TIME (s) HEIGHT (cm)
POINTS PLOTTED
BEST FIT LINE OR CURVE
TITLE (DEPENDENT vs. INDEPENDENT)
