scatter diagram

a graphical figure in which two axes are plotted at right angles to each other, the independent variable on the x (horizontal) axis and the dependent variable on the y (vertical) axis. Each individual or object is then measured for these two variables, for example, age (x) and weight (y), and the position marked on the correct coordinates of the diagram, producing a series of scattered points. These may be given a ‘line of best fit’ by REGRESSION ANALYSIS.

scatter

1. the diffusion or deviation of x-rays produced by a medium through which the rays pass.
2. the distribution of two variables in relation to each other, e.g. the numbers of a population in terms of time, place or any other variable.

back scatter
backward diffusion of x-rays.
scatter diagram
a graphic representation of a scatter of two variables.
scatter radiation
the scattering of radiation in all directions as a result of interaction between the beam of the x-ray and the patient. See also compton effect.
