A statistical map would be a great way to visually display our data. Methods are presented for summarizing data numerically, including presentation of data in tables and calculation of statistics for central tendency, variability, and distribution. Clearly there is much overlap of the area of graphical data analysis and the area of graphical data presentation, but there are many special considerations that arise when a graph is made to present data to others. The appropriate type of representation for a collection of data depends in part on the nature of the data, such as whether the data are numerical or nonnumerical.

Tabulation i.e. HISTORY . it is used in many academic and professional disciplines but most widely so in the field of mathamatics,medicine and the science. Two separate line diagrams showing fluctua­tions in the values of exports and imports of India during (1987—96) are shown below: In the diagram drawn above the successive years from the table are shown horizontally and the corresponding values of export and import are shown vertically and the points are located separately on the plane from the middle of the respective years and the lacus of those points exhibit the trend along the line diagrams.

Histogram: Graphically, one of the most important and useful methods of presenting the frequency distribution of both continuous and discontinuous types is called histogram. It is advisable to use custom animation to show the callouts one at a time. Another example is Tufte (1983), in which some new ideas about graph design are presented. Two or more (but finite number of) line segments can also be drawn on the same quadrant when information on different variables over the same period or time are simultaneously represented using the same unit of measurement along the same axis. Further, graphs of statistical data clearly bring out the relative importance of different figures, the trend or tendency of the values of the variables involved can be studied too. This kind of a diagram is drawn for a fre­quency distribution of a continuous variable in terms of cumulative frequencies of both the types (more than or less than type). The reader acquires information through reading the gathered data. These techniques are easy to do, but I’ve rarely (if ever) seen them all demonstrated so well in a single talk.
