  1. Graphing with Mrs. Ellerman

  2. Data • What is data? Examples? • Information of observations (pennies) • How is data valuable to scientists?

  3. Data Tables • What is a data table? • A way to organize data in columns so it is neat and readable. • Where is the title?

  4. Data Tables • What is a variable? • Describes what is being collected in a data table. • What is a unit? • Describes how the information was collected. • Why is it important to have variables and units included on a data table?

  5. Ordered Pairs • What are ordered pairs? • Two pieces of data directly corresponding to one another. (0,20) (2,23) (4,35) (6,61) (8,71) (1,21) (3,27) (5,45) (7,69) What is the best way to identify an ordered pair? Pg.7 How are ordered pairs related to data tables?

  6. Data Tables • What does a complete data table have? • A descriptive title • Variables describing WHAT information has been collected • Units telling HOW the variables were measured • Data collected in ordered pairs • All work is NEAT and READABLE

  7. Vocabulary Review! • _____Jargon • _____Data • _____ Data table • _____ Title • _____ Variable • _____ Unit • _____ Ordered pairs • Information of observations • A way to organize data in columns so it is neat and readable. • Two pieces of data directly corresponding to one another. • A specialized vocabulary used to describe things in a specific field of study. • WHAT information is being collected • A brief way to describe the content of a book, graph, or data table. • HOW information was measured GOOD LUCK! Done!

  8. How to read a graph • Title • Data • Variables • Units • Horizontal axis • Bottom (X) • Vertical axis • Side (Y)

  9. How are data tables and graphs similar? • The same descriptive title • The same variables and units • The same data

  10. Intersection Crossing of two data lines Data point Place where two data lines cross Intervals An even spacing of the numbers along the axis of a graph PRACTICE! How do you plot data on a graph? Y-axis X-axis

  11. Get Your Graph Paper! • Draw your horizontal and vertical lines • Look at the data and decide which variable is the most consistent. It goes on the horizontal axis. • Number each axis in even intervals for the data you are graphing. • Plot your data from your data table onto your graph. • Put a title on your graph.

  12. Line Graph VS. Bar Graph Green Plant Green Plant Growth (in.) Time (years)

  13. Multiple Line Graph • A multiple line graph is used when comparing several different experiments utilizing similar data.

  14. Lets Practice! Look in your packet for tips!

  15. _____Graph _____Horizontal axis _____ Vertical axis _____ Intersection _____ Data Point _____ Plotting _____ Intervals _____ Line graph The axis that goes across the bottom of the graph The axis that runs up and down on the side of the graph The place where the data lines cross (or intersect) A graph drawn using data points Finding the data point for an ordered pair A picture of information in a data table An even spacing of the numbers along the axis of the graph The crossing of two lines when graphing Vocabulary Review! GOOD LUCK! Done!
