Investigating Scatter Plots Scatter plots – show correlations (relationships) between two different pieces of data.  dependent variable (y’s or range)

Types of Relationships. Line of Best Fit A line of best fit is a straight line that best represents the data on a scatter plot. This line may pass through.
