OBSERVATIONS: often are recorded in a data table
INTERPRET (make inferences of) your DATA TABLE by performing anANALYSIS using GRAPHS
What is the relationship between Rabbits and Years for the following example: GRAPH IT
YEAR # of RABBITS
1990 500
1992 600
1994 800
1995 900
1996 1200
1998 1800
ANALYZE your DATA Step One: Identify your problem:
What is the relationship between the years and the number of rabbits
Step Two: Draw your Axis
Y-axis
