Answer» Diagrammatic representation of data : An attractive representation of statistical data is provided by charts, diagrams and pictures. Furthermore, any hidden trend present in the given data can be noticed only in this mode of representation. Bar charts, histograms, pie charts, and boxplots (box and whiskers plots). Two common types of graphic displays are bar charts and histograms. Both bar charts and histograms use vertical or horizontal bars to represent the number of data points in each category or interval. |
