# graphical presentation of data

It always depends on the type of information in a particular domain. presentation of statistical data. Graphical representation is the visual display of data using plots and charts. To complete the polygon, join the point at each end immediately to the lower or higher class marks on the x-axis. Diagrams can present the data in an attractive style but still there is a method more reliable than this. The point where the perpendiculars intersect is the position of the point P. We denote it as follows (3, 5) or (abscissa, ordinate). Some of them are as follows: There are certain rules to effectively present the information in the graphical representation. It helps to study the relationship between two variables where it helps to measure the change in the variable amount with respect to another variable within a given interval of time. It allows the viewer to compare data relating to two different time-periods or regions. A graph refers to the plotting of different valves of the variables on a graph paper which gives the movement or a change in the variable over a period of time. Charts, graphs, and images 4. In Statistics, a graphical representation is a visual display of data in the form of a diagram or graph. The graph is easily understood by everyone without any prior knowledge.
