Students create a simple scattergraph to see the correlation between two variables.
Use it to review the required components of an effective graph from Activity 4. The major criteria are in italics on the sample graph in Teacher's Model of a Scattergraph, Appendix 5.2. Draw a line of best fit. The line should follow the trend of the dots. It is not necessary for the line to be absolutely accurate but it should follow the overall pattern of the dots.
