scatterplot

n. a graphical representation of the relationship between two continuously measured variables in which one variable is arrayed on each axis and a dot or other symbol is placed at each point where the values of the variables intersect. The overall pattern of dots provides an indication of the extent to which there is a linear relationship between variables. A round mass of points shows no linear relation, an elliptical cloud of points with a positive slope shows a positive relation, and an elliptical cloud with a negative slope shows a negative relation. Outlier points are also clearly visible. Also called dot plot; scattergram. See also regression line.
