2 How to Read, Develop, and Interpret GRAPHS!  OBSERVATIONS: often are recorded in a data table  INTERPRET (make inferences of) your  DATA TABLE by performing an  ANALYSIS using GRAPHS

3 What is the relationship between Rabbits and Years for the following example: GRAPH IT YEAR # of RABBITS 1990500 1992 600 1994 800 1995 900 1996 1200 1998 1800

4 ANALYZE your DATA Step One: Identify your problem: What is the relationship between the years and the number of rabbits

5 Step Two: Draw your Axis Y-axis X-axis

6 Step Three: Label Your X Axis: Y-axis X-axis What is the relationship between years the number of rabbits Years 1990 1992 1994 1996r 1998 2000

7 Step Three: Now Label Your Y Axis: Y-axis X-axis What is the relationship between years and the number of rabbits YEARS RABBITS 700 600 800 900 500 1000 1990 1992 1994 1996r 1998 2000

8 Step Three: Now Label Your Y Axis: Y-axis X-axis Was there enough room to label your y axis completely for this problem? YEARS RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996r 1998 2000

9 Step Four: Now Plot Your Points Y-axis X-axis Years RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996 1998 2000

10 Step Four: Now Draw Your LINE Y-axis X-axis Yearss RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996 1998 2000

11 Step Five: Answer the Problem Y-axis X-axis Years RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996 1998 2000 What are the characteristics of the Red Star?

12 Step Five: Answer the Problem Y-axis X-axis Years RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996 1998 2000 What is the x coordinate and the y coordinate of the red star?

13 Step Five: Answer the Problem Y-axis X-axis Yearss RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996r 1998 2000 What is the x coordinate and the y coordinate of the green dot

14 Step Five: Answer the Problem Y-axis X-axis Years RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996 1998 2000 What are the characteristics of the Green Star?

15 Step Five: Answer the Problem Y-axis X-axis Years RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996 1998 2000 What would you estimate the rabbit population to be in 2000?

16 Step Five: Answer the Problem Y-axis X-axis Years RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996r 1998 2000 What would be the x and y coordinates for your prediction of the rabbit population in 2000?

17 Step Five: Answer the Problem Y-axis X-axis Years RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996r 1998 2000 This ia called an EXTRAPOLATION

18 Step Five: Answer the Problem Y-axis X-axis Years RABBITS 1200 900 1500 1800 600 2100 1990 1992 1994 1996 1998 2000 This is called an INTERPOLATION
