What is a variable?In statistics, a variable has two defining characteristics:A variable is an attribute that describes a person, place, thing, or idea.The value of the variable can "vary" from one entity to another.For example, a persons hair color is a potential variable, which couldhave the value of "blond" for one person and "brunette" for another. Usually, graphs are used to present time series and frequency distributions. The following are the chief objectives of diagrammatic representation of data: (i) To present the data an attractive and impressive manner: The numerical data, as a matter of fact, are very much boring and distractive in nature.They do not appeal to the mind of a common man. Q.- Briefly Explain the Basis or Methods of Classification. A graph lacks complete accuracy of facts. Together, they are the coordinates of the point P. The four parts of the plane are Quadrants. The transformation of data through visual methods like graphs, diagrams, maps and charts is called representation of data. The basic graphic notation elements of DSDs are boxes which represent entities. The viewer does not require prior knowledge of mathematics or statistics to understand a graph.

A graph is a sort of chart through which statistical data are represented in the form of lines or curves drawn across the coordinated points plotted on its surface. Analyzing map legends to better understand the nature of the representation of data on the map (e.g., classification values and break points of a choropleth map, methods for determining different classification values, review the histogram of the data to see how data are represented in another form in addition to the mapped version). The example on the next page, which I created using Tableau Software, is a good example of a map that was thoughtfully designed for displaying data. 3.6.1 Raster data In a raster representation geographic space is divided into an array of cells, each of which is usually square, but sometimes rectangular (Figure 3.9). Because geographic data often fail to meet distributional assumptions necessary for classical statistical procedures, geographers have been at the center of attempts to develop distribution-free methods for estimating statistical relationships among variables. 10. Combination of Tables and Graphs. Think of geographic representation in GIS as a 4 step process: Real world-Data model-Data structure-machine code Geodatabase Native data structure for ArcGIS and is the primary data format used for editing and data management Data structure diagrams are most useful for documenting complex data entities.

The point where the perpendiculars intersect is the position of the point P. We denote it as follows (3, 5) or (abscissa, ordinate). The arrow symbol represents relationships. We cannot use a graph in support of a statement. The arrow symbol represents relationships. Notice how the geographical features have been pared down and visually subdued to allow the data to stand out. Distinct types of a geographic information system are explained with the aid of a diagram: Fig1: Types of Geographic Information System.
