Description
Graphical methods, ways of showing numbers as geometric figures, are the subject of this 1911 Encyclopaedia Britannica article. The methods turn data from measured events into pictures. Their simplest use is with tables, such as those found in statistics. Most such tables pair one value of one quantity with one value of another. The article explains how such a table becomes a graph.
Two axes are drawn at right angles, crossing at a point called the origin. Distances along one axis stand for values of the first quantity. Upright lines are raised at those points, and distances along them stand for the paired values. A curve through the points is the graph. At a glance, the curve shows the main features of the table. A poor corn yield shows as a dip, a rich one as a peak. Graphs also let readers compare sets of figures with ease.
