# Interpreting Scatter Graphs

Students learn how to use the line of best fit to estimate missing data values.  To extend on this in the development phase students go on to consider what it means for two measurements to have a positive, negative or no correlation.
##### Differentiated Learning Objectives
• All students should be able to determine whether two measures correlation using a scatter graph.
• Most students should be able to plot a line of best fit from a scatter graph and use that to determine the strength and type of correlation between two measures.
• Some students should be able to use a line of bit fit and their understanding of correlation to estimate one measure when the other is provided.
