  1. Graphing Wakefield 2011-2012

  2. Choosing the Correct Type of Graph • Bar Graph • Compare data quickly & easily • Such as grade distribution • Growth of plants

  3. Choosing the Correct Type of Graph • Pie Graph / Chart • Showing Percentages • % of student body who picked certain entrees @ lunch • % of a total budget to be used on certain items

  4. Choosing the Correct Type of Graph • Line Graph • Looking @ changes over time • The number of swimsuits sold each month • The change in your height throughout the year

  5. Line Graphs • In science class you use a line graph most of the time • To compare variables • (Variables are things in an experiment that change)

  6. Labeling Graphs • All parts of a data table must be included in a graph • Graphs are simply pictures of the info collected in a data table

  7. Labeling Graphs • There are 2 axes on a line graph • Horizontal axis / x-axis • Runs along the bottom of the graph horizontally • Vertical axis / y axis • Runs along the side of the graph vertically / up & down Y X

  8. Labeling Graphs • Each axis must be labeled with the proper variable • X axis indicates the Independent variable • The variable that changes in an experiment • Y axis indicates the Dependent variable • The variable that is observed and is changed by the independent variable Y X

  9. Labeling Graphs • Each axis must be labeled in the proper units • Meters – hours – seconds – degrees Celsius • Each entry should be spaced out in even intervals • The Rangeon a graph is the difference between the largest and smallest numbers in the data • The Interval is the range divided by the # of lines • When constructing your graph, make sure to space your intervals so that you take up as much of your graph as possible.

  10. Plotting Data Points • The #’s in a data table are organized in pairs • Called Ordered Pairs

  11. Interpolation and Extrapolation • Interpolation • A prediction made between known data points • Extrapolation • A prediction made beyond known data points

  12. Graphing Vocabulary • Bar Graph • Data • Data Table • Dependent Variable • Extrapolation • Graph • Independent Variable • Interpolation • Interval • Line Graph

  13. Graphing Vocabulary • Ordered Pairs • Pie/Circle Graph • Range • Title • Units • Variables • X-axis • Y-axis
