A scatter plot contains all the combinations of values of two variables that constitute the different observations comprised in a dataset. Those pairs of values are in turn coordinates in a graph. <em>(image 1)</em>
A line of best fit can be represented in the scatter plot to both study and show the relationship between the two varibles<em> (image 2)</em>. For example, when linear correlations are estimated, the best-fit technique that should be used to compute the line is the linear regression.
