Discrete and Continuous Measurementues between them are not used. It is possible to have 3 or 4 children in a family but not 3 1/2. We may buy 40-, 60- or 100-watt lamps but not 43- or 68-watt. A shop will sell shoes of size 5 or 6 but not 5.2. The dictionary defines discrete as ‘separate, individually distinct, discontinuous’. It is the last of these which should be emphasised.

Further Graphical Methods of Presenting Data two or more graphs have to be plotted together. If the scale is too small a second difficulty arises in plotting straight lines for regression or trend, the problem being the determination of direction which a larger scale might ameliorate.

Die Zukunft Europas in einer Welt im Umbruch a theoretical law in the form of an equation. The imperfections of measurement in addition to the influence of other factors can cause divergencies between theory and practice. Study of these errors has led statisticians into advanced techniques and the purpose of this chapter is to lay a simple fo
