  1. Bellringer 11/01 1) a) What axis is the dependent variable on? b) What axis is the independent variable on? 2) If you were given a table, how would you know what was the independent variable 3) What should be at the top of every graph? (how do you write this?

  2. Analyzing Graphing If you are good (less than four names on the board), the class can earn candy at the end of class.

  3. Located: Oxford, MS • 16,786 students • Avg. ACT: 20-25 • Acceptance rate: 79%

  4. Mascot: Rebels, Rebel Black Bear • Famous for: James Meredith, great football program, Michael Oher (Blind Side), Archie Manning, large Greek life

  5. Analyzing Graphs • The past few days we have seen many graphs and even made some. • Objective: Achievers on the ROAD to college will be able to use (analyze) these graphs to give you information you need.

  6. 1) Identify The type of Graphs • There are 3 Types of Graphs • (1)Line Graphs • (2)Bar Graphs • (3)Pie Charts • (3.5)Tables

  7. 2) Identify Variables • Identify the Independent and Dependent Variables • For Bar Graphs: • The (4)Independent Variable is on the x-axis • The (5)dependent Variable is on the y-axis

  8. 2) Identify Variables • Identify the Independent and Dependent Variables • For Line Graphs: • The (6)independent variable is on the x-axis • The (7)dependent variable is on the y-axis

  9. Find the Independent/ dependent Variables

  10. Find the Independent/ dependent Variables

  11. 3) Read the Question • There are 3 things you may have to find in a question: • Tell something about the graph: (8)Just pick out information • How many 5th graders like Grapes? • How many 6th graders like apples?

  12. 3) Read the Question Make a prediction: You will not have the number you need on the graph, (9)you will have to find it out on your own How many guppies will there be if it is 30 degrees?

  13. 3) Read the Question • Draw a conclusion: From the graph you’re going to have to be able to tell what is happening • As the (10)INDEPENDENT VARIABLEincreases/decreases the (11)DEPENDENT VARIABLEincreases/decreases

  14. Duckweed is a plant that grows on the surface of ponds. Duckweed has leaf-like structures called fronds. A student conducts a lab investigation on duckweed growth and creates the graph shown above. Which of these is a valid conclusion based on the data from this investigation? A. The number of fronds more than doubled between Days 2 and 4. B. The number of fronds increased quickly because the plant has a short life span. C. The number of fronds is related to the number of hours of sunlight each day. D. The number of fronds increased at a constant rate between Days 1 and 5.

  15. II) Tables: • Eliminate Constants: (12)Cross them out in the graph • If the (13)numbers are not changing CROSS THEM OUT! They are Constants or controls • There is little information to gain if the numbers stay the same!

  16. What are the constants here?

  17. II) Tables • Find the variables: Fill in the (14)cause and effect. • (15)INDEPENDENT VARIABLEwill cause the (16)DEPENDENT VARIABLE to happen • Typically the IV is going to be in (17)even increments like: 2,4,6,8 or 3,6,9,12 or 5,10,15,20 • Typically the DV is going to be (18)a lot of weird numbers

  18. Find the Variables

  19. II) Tables Read the question • Draw Conclusions: • As the (19)INDEPENDENT VARIABLE increases/Decreases the (20)DEPENDENT VARIABLE increases/Decreases • What is the experiment for: • How does (21)INDEPENDENT VARIABLEeffect (22)DEPENDENT VARIABLE

  20. Practice: Graphs

  21. Practice: Graphs A scientist studied 5 different types of soil and counted the number of worms living in each type. Her results are shown in the bar graph above. Which statement best describes the scientist’s results? A. Worms have similar frequencies in these types of soil B. Worms were most often found in the muddy soil habitat C. Worms are suffocated by clay soils D. Worms search for moisture in sandy and loamy soil.

  22. Practice: Graphs

  23. Flightless Mormon crickets often move in large groups. The graph shows the survival rate of crickets moving in large groups and of some crickets that were moved away from the groups. Which of these inferences about Mormon crickets is most likely accurate? A. Mormon crickets within a group survive only two days. B. Mormon crickets away from a group successfully reproduce. C. Mormon crickets away from a group return to it for protection. D. Mormon crickets within a group are less likely to be eaten by predators.

  24. Independent Practice • Complete the Independent practice work on your own. • If not done, complete it for homework • It will be collected and counted as a HOMEWORK GRADE
