diagrammatic representation of data ppt

Graphical Representation is a way of analysing numerical data. These diagrams are used in a situation where two or more related categories are to be compared simultaneously. An ogive is another statistical tool primarily used for finding out different quartiles in a distribution. Define diagrammatic. The height of the Bar usually corresponds to the required value. It enables us to think about a statistical problem in visual terms. DIAGRAMMATIC REPRESENTATION OF DATA - Part II. Practically, the height of each bar placed vertically represents the value of the variable on the identical class interval shown horizontally. Sumit Thakur Diagrammatic Representation of LAN Sumit Thakur Sumit Thakur [email protected] Administrator I am an Indian Blogger. It is a mathematical picture. Meaning Of Graphical Representation Of Data A picture is said to be more effective than words for describing a particular thing. However, compared to tabulation, this is less accurate. TOS4. In statistical analysis, diagrams are of no use. Besides the tabular form, the data may also be presented in some graphic or diagrammatic form. 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. These diagrams are nothing but the use of geometrical figures to improve the overall presentation and offer visual assistance for the reader.Â. Our mission is to provide an online platform to help students to discuss anything and everything about Economics. All graphical representations of data can be a diagram, but all diagrams are not a graph. Selection of the appropriate diagram actually depends on the nature of the raw data available and the purpose or the area in which it will be applied. Let us represent a simple pie diagram below constructed with the usual method prescribed and followed for its computation by converting the following information into that diagram. Watch Now. Let us imprint simple and suitable examples of bar diagrams be­low: Volume of population in a number of states in India in 2001 is given below—represents the data with the aid of vertical bars. When the values of the variable under consideration change at a constant rate over the same successive time intervals, the diagram will take the shape of a straight line. Cumulative frequency of less than type is zero for the lowest given value of the variable and similarly cumulative frequency of greater than type is zero for the highest value of the variable considered. We will discuss the conceptual points involved in all of them. For drawing it correctly, we convert the particular given values of the variable as a percen­tage of the total value of the variable. They are objects, mainly geometrical figures such as lines, circles, bars, etc. Disadvantages of Graphical Representation of Data. Commerce Upgrade to Infinity. The feeds will do you good because best hairstyles is here. within a geographical territory. They do not provide detailed information. Diagrams may be less certain but are … Diagrams are based on scale but are not confined to points or lines. Only artist can draw multi-dimensional diagrams. A line represents the sequence of data connected together against a particular variable.Â. Diagrams do not present the small differences properly. Dec 20, 2020 - Diagrammatic Representation of data - Presentation of Data, Business Mathematics & Statistics B Com Notes | EduRev is made by best teachers of B Com. 2. The entire area in the circle is subdivided into a number of parts by several radii which are separately related to the total area of the circle and also maintain the same proportional relation with the angle at the centre. It is easy to understand and it is one of the most important learning strategies. What is. Improves the Representation of Data as a Whole. It exhibits the relation between data, ideas, information and concepts in a diagram. Sorry!, This page is not available for now to bookmark. Data-centered architecture; Also See: DNA Computing Seminar and PPT with PDF Report. There are several advantages in the presentation of data with the various types of diagrams. Privacy Policy3. Datasets which require comparison of its elements in between themselves use the application of diagrams for representation. make the use of diagrams across the world.
