Title: PICTORIAL REPRESENTATION OF STATISTICAL DATA
Abstract: This chapter discusses a few regularly used pictures and diagrams, while the slightly more complicated matter of graphs forms. It also discusses the pictograms. Simple outline figures are used to represent quantities or values. For example, if the statistics relate to the changing level of unemployment over 10 years, the pictogram could be drawn as a number of human outlines, each one representing a given level of registered unemployed. Bar charts seek to relate information to the horizontal or vertical length of a bar or thick line. They are of two main types, those that compare statistics for a given period of time and those that compare them over a succession of periods of time. Gantt charts plays an important role in business statistics. The object of the Gantt chart is to relate actual performance to planned or anticipated performance. One of the simplest methods to represent the way in which a whole statistical collection breaks down into its component parts is to use the pie diagram. The pie chart depicts the component parts of any set of statistical data as slices of pie.
