  1. Graphs in Science You Can Do It!!!

  2. Graph • A picture of your data that reveals patterns or trends that words or data tables cannot.

  3. Bar Graphs

  4. Line Graphs

  5. Cool

  6. Yes Science Rules

  7. Line Graphs • Are used to display data to show how one variable (DEPENDENT VARIABLE) changes in response to another variable (INDEPENDENT VARIABLE).

  8. Plotting a line Graph • 1. Draw the axes • Horizontal axis (x-axis): Independent Variable • Vertical axis (y-axis): Dependent Variable • 2. Label the axes: • Independent Variable (x ) and Dependent Variable (y) • Include UNITS of Measure • 3. Create a scale • Needs to cover the ranges of values from your data • Space numbers equally along axes

  9. Plotting a line Graph • 4. Plot the data • Using coordinate pairs (data) • Data Point: the point showing the location of the coordinate pairs • 5. Draw a line of BEST FIT • A smooth line that reflects the general pattern of a graph • 6. Add a title • Identify the variables or relationship shown in the graph.

  10. Line of best Fit Emphasizes the overall trend shown by all the data taken as a whole

  11. Slope • The slope of a graph line tells you how much y changes for every change in x.
