The Design of Ballantines.
The widespread availability of computational graphics for personal computers has greatly increased the potential for visual display of research data. The correlation between two variables can be represented graphically by using circles to represent the variance associated with each circle, and by letting the overlap between the circles be proportional to the squared product-moment correlation between the variables. A procedure is given for locating the circles so that this relation is fulfilled. The method is extended to the three-variable case. The extended case can be used to construct graphical representations called ballantines. The PASCAL computer program for the ballantine procedures is appended. (Author/BS)
