Scatterplot

A scatterplot is a way of representing the scores of a group of clients in a graphic fashion. A scatterplot shows two scores (X and Y) for each individual and plots the individual in terms of the X and Y scores.

Scatterplots are a very useful way of showing the relationships of two variables, X and Y, for a group of individuals. Each point plotted on a scatterplot represents a single person who has scores that can be read off the X (horizontal) axis and Y (vertical) access of the plot.

Sometimes our plots show individuals who are identified as belonging to several different groups (for example, males and females). Usually the plots are color-coded when more than one group of persons is plotted.

Scatterplots should be examined to see if there appears to be a systematic relationship between X and Y variables such that high (or low) scores on the X variable are systematically associated with high (or low) scores on the Y variable.
