Another form of graphical presentation of data is the scatterplot, which we discussed in Chapter 11. A scatterplot is, in essence, a simple plotting, in two dimensions, of observations in one's dataset. We have heretofore stressed the virtues of a scatterplot for the investigator, as, for example, a means of getting a first glimpse of the relationships that may exist within the data. Can a scatterplot help one to communicate effectively to one's audience? Undoubtedly there are cases where a scatter plot will work but in limited circumstances. Two obvious extreme circumstances are when one wants to visually show an audience that (1) there is no relationship in the data, or (2) there is a clear relationship in the data. Beyond these extremes, a scatterplot probably does not serve the communicative function as effectively as would simply reporting descriptive or inferential statistics.
