Karnataka 1st PUC Statistics Question Bank Chapter 4 Diagrammatic and Graphical Presentation of Data 1st PUC Statistics Diagrammatic and Graphical Presentation of Data Two Marks Questions and Answers. • Graph is a representation of information using lines on two or three axes such as x, y, and z, whereas diagram is a simple pictorial representation of what a thing looks like or how it works. lakshyasingh1491 lakshyasingh1491 Secondary School Economy 8 points What are the advantages of diagrammatic presentation of data. What type of data is most appropriately represented by each of the representations you listed above? It is easy to understand and it is one of the most important learning strategies. So if there is a priority for accura… Table facilitates comparison. 4. Outer Join can be used to prevent the loss of data from the tables. Diagrammatic representation can be used for both the educated section and uneducated section of the society. Learn vocabulary, terms, and more with flashcards, games, and other study tools. But graphs make the data more meaningful and hence, they are very much used by statisticians and research scholars in the analysis and interpretation of data. Special knowledge: Graphs helps easy understanding but to prepare graphs an individual need to have special knowledge. In this short article I will try explain what they are and what the differences are. The highest level of abstraction for the data model is called the Entity Relationship Diagram (ERD). An intelligent agent is a goal-directed agent. and questions that rapidly increase in difficulty. Thus, this explains the basic difference between DFD and flowchart. Differences Between Diagrams and Graphs The following are the major distinctions between diagrams and graphs. Graphical Representation of Data . A conceptual graph (CG) is a formalism for knowledge representation.In the first published paper on CGs, John F. Sowa used them to represent the conceptual schemas used in database systems.The first book on CGs applied them to a wide range of topics in artificial intelligence, computer science, and … Infographic. Types of Outer Join : Outer join is again classified into 3 types: Left Outer Join, Right Outer Join, and Full Outer Join. Diagrams and graphs help to compare and analyze information between different sets of data. It is a graphical representation of data requirements for a database. Graphical representation can be used for both the educated section and uneducated section of the society. Reasonator; PetScan; Scholia; OpenStreetMap; Locator tool; Search depicted; English: A diagram is a plan, drawing, sketch or outline … Charts and graphs now play an important role in data presentation. Programmers often use it as a program-planning tool to solve a problem. It requires a lot of skill to prepare, and some skill(s) to understand. Ø The Frequency Polygon is a curve representing a … Errors and Mistakes: Since graphical representations are complex, there is- each and every chance of errors and mistakes.This causes problems for a better understanding of general people. Coverages use a set of feature classes to represent geographic features. Diagrammatic presentation of data translates pretty effectively the highly complex ideas included in numbers into more concrete and quickly understandable form. Difference Between DFD and Flowchart Definition. A bar graph is a graphical representation of the data in the form of rectangular bars or columns of equal width. 4. Usually, graphs are used to present time series and frequency distributions. A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). Diagrammatic reasoning tests are designed to be challenging, in order to differentiate between candidates and to identify the maximum performance they are capable of. Infographics often combine statistics with a narrative or story. Data flow diagram describes anything about how data flows through the system. Main Difference. But mentioning superset doesn’t look appropriate if you are going to use this difference in exam. The following are the cardinal points of difference between a tubular, and a diagrammatic representation of data: (i) Visual appeal: The tabular presentation of data does not have any visual appeal whereas the diagrammatic presentation of data has a visual appeal, and as such, it proves to be more impressive for a layman. Frequency Polygon. • Values of mean and median can be calculated through graphs which is not possible with diagrams, • Graphs are drawn on graph paper whereas diagrams do not need a graph paper, • For frequency distribution, only graphs are used and it cannot be represented through diagrams, Filed Under: Mathematics Tagged With: diagram, diagrams, graph, graphs, Visual representation. A data-flow diagram has no control flow, there are no decision rules and no loops. a map, graph, chart or diagram), while an infographic often contains multiple data visualizations. Furthermore, any hidden trend present in the given data can be noticed only in this mode of representation. Anyone can prepare, anyone can understand. An infographic is a visual representation of facts, events, or numbers. Diagrams leave a lasting impression. 3. 6. Step 1: Partition the data range into classes or bins. Charts represent a large set of information into graphs, diagrams, or in the form of tables, whereas the Graph shows the mathematical relationship between varied sets of data. diagrammatic and graphical representation of data 1. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. A bar graph is a pictorial representation of data that uses bars to compare different categories of data. Only artist can draw multi-dimensional diagrams. Facilitate Comparison. The graphical view is vastly used in every type of data or report. Every type of graph is a visual representation of data on diagram plots (ex. Here we provide you with the top 6 difference between Graphs vs Charts. We have come a long way since 1801. This means that diagram is only a subset of graph.’. A second key difference is that infographics contain additional elements like narrative and graphics. We are too well aware of the use of diagrams to explain information and facts that are presented in the form of text.
But graphs are not attractive to eyes and hence, generally, they are not used in advertisement and publicity. If you need to explain the parts of a machine or the principle of its working, it becomes difficult to make one understand the concept through text only. Diagrams do not present the small differences properly. Demerits (or) limitations 1. (vi) Diagrams are rarely used to present frequency distributions. Apart from diagrams, Graphic presentation is another way of the presentation of data and information. The main difference between Diagram and Chart is that the Diagram is a plan, drawing, sketch or outline to show how something works or the relationships between the parts of a whole and Chart is a graphical representation of data. Agents interact with the environment through sensors and actuators. Write down the different data representations (charts, graphs, diagrams) you remember.
(adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Tabular Mode of presentation is the most accurate mode of presentation of data. It is the simplest one and easily understandable among the graphs by a group of people. Specific operations based on the data can be represented by a 2. (v) Diagrams are better drawn on plain papers but graphs are accurately drawn on graph papers. 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. Both are visual representations of data. As the different kinds of graphs aim to represent data, they are used in many areas such as: in statistics, in data science, in math, in economics, in business and etc. (iii) Helpful in Making Comparisons: The presentation of data in the form of diagrams helps in making comparisons between two or more groups or two or more periods.
