  1. Tables and Graphs

  2. “I CAN” Statements Tables and Graphs • Recognize the parts of a data table [L1] • Construct a data table [L2] • Recognize the 3 main types of graphs [L1] • Memorize which axis is to be used to represent variables [L1] • Predict -given specific data- which type of graph is more appropriate to use [L2] • Graph data in its appropriate form/type [L2] • Distinguish between extrapolation and interpolation [L2]

  3. Columns CELL Rows GRID

  4. Title Headers Impact of Rain on Weight harvested Units

  5. Title Units Area and Depth of Oceans Headers “Global Ocean” is sometimes divided in 5:Antarctic Ocean

  6. BAR GRAPHalso known as HISTOGRAM • Better suited for data collected by counting • Shows a relationship b/t 2 groups, but one does not affect necessarily the other • One set of data is divided into categories, events, places… • Examples  sales/profits per month  number of earthquakes and location over a 4 weeks period  average rainfall

  7. PIE / CIRCLE GRAPH • Represents the different parts of a whole / how categories of information compare to each other • Example:  chemical composition of our atmosphere

  8. Pie Graph Composition of Earth’s Crust 47% 27% 8% 5% 3.5% 3% 2.5% 2% 1.5%

  9. LINE GRAPH • Continuous set of data showing how one factor [variable] affects another • IMPORTANT CONVENTION to remember • X = horizontal = input = independent Δ • Y = vertical = output = dependent Δ

  10. LINE GRAPH • Best-fit line rather than data connected “dot-to-dot” • BFL is a straight line or smooth curve that satisfies most of the points. • it will show TRENDS that allows to make predictions “Dot-to-dot” Best-fit line

  11. Relationship b/t Depth of Ocean floor and Age of Formation

  12. The final graph is also known as Standard Graph • From a Standard graph, one can further find information that was NOT collected during experimentation. • Interpolation: values that fall within the collected data • Extrapolation: values that fall outside the collected data

  13. The independent variable is always placed on the vertical axis • True • False

  14. Which one would you trust the most?Extrapolation or Interpolation? ?

  15. Which type of graph is best suited to display the amount of iron ore in four different countries? • Bar • Pie • Line

  16. The data are from an experiment to find out the speed of an object dropped from a tall building. Which type of graph would be the best way to display this information • Bar • Pie • Line

  17. According to these data, about how fast would the object be dropping after 11 seconds? • 90 m/s • 100 m/s • 110 m/s • 120 m/s

  18. PICK A STUDENTWhat independent variable could have been added to this experiment?

  19. Which type of graph is best suited to display the major gases found in Earth’s atmosphere? • Bar • Pie • Line

  20. Which type of graph is best suited to display the relationship between distance traveled and amount of gas used? • Bar • Pie • Line
