Basic Rules

  • Use a pencil (so you can fix mistakes)
  • Use a ruler to draw the axes
  • Put an arrow on the end of each axis

X and Y Axes

  • The x-axis has the independent variable
    • The thing you change
  • The y-axis has the dependent variable
    • The thing that you measure

Labelling the Axes

  • Title each axis
  • Give each axis a unit

Title Your Graph

  • Give your graph a descriptive title

The Origin

  • Both axes should start at zero
  • This is called the origin

Adding Data Points

  • Use crosses, not circles or anything else!
  • Like battleships! Data points line up exactly with the axis

Trendline / Line of Best Fit

  • Goes through or nearby most points
  • Shows the general trend of the data
