Note: Independent variable is plotted on the horizontal axis and dependent variable is plotted on the vertical axis

Video 3: Creating a Scatter Plot with a Break on the Axes
First: Draw the small grid lines for labelling your axes (same distance between the grid lines)
Second: Label the grid lines with the same jump in numbering (every 2's, every 10's or every 100's)
Don't label the axes with the numbers given in the table. You approximate those numbers along the axes when plotting!
You may break an axis to skip unnecessary lower values using the "lighting symbol" at the beginning of the axis.
