Scatter Graph: A graph of plotted points that show the relationship between two sets of data.    

Correlation: The relationship or connection between two sets of data. 

Line of best fit: is a line that goes roughly through the middle of all the scatter points on a graph. 

Outliers: are values that lie outside the other values. 

Interpolation: is where you use a line of best fir for a value that is within the plotted points.    

Extrapolation: is where you use the line fo best fir for a value that is outside the plotted points.
