Exam Tips for Scatter Graphs
- Choose appropriate scales - use most of the grid space
- Label axes clearly with variable names and units
- Plot points accurately - use a sharp pencil and read coordinates carefully
- Identify correlation type - strong/weak and positive/negative/none
- Line of best fit should be straight and balance points above/below
- Ignore outliers when drawing the line of best fit
- Extend the line appropriately for making predictions
- Be cautious with extrapolation - state that it's less reliable
