Describe the meaning of the graph. 4) Notice that the scatter plots in #2 and #3 don’t appear to be more spread, but there is a significant difference in their correlations. Unless there is a convenience function or plot() method for whatever plot you wish to make, it can be unacceptably tedious to make plots using only base R, especially if they are complex plots. 3.) Plot the points, then decide if the scatter plot shows positive, negative, or no correlation. Here is an example: Scatter plots can show positive, negative, or no correlation. A.
