Graphical Representation of Data: Part 1 (Diagrammatic Data Representation: Line Chart, Bar Diagrams and Histogram) Graphical Representation of Data / Variables. d] Tabulated data can be easily presented in the form of diagrams and graphs. simple bar diagram to represent the data rectangular bars of equal width and height proportional to the magnitude items are drawn with proper scale. Statistics is a crucial process behind how we make discoveries in science, make decisions based on data, and make predictions. Bar diagrams for comparing different components of a variable and also the relating of the components to the whole. Finally, we use Divided Bar charts or Percentage, Bar diagrams for comparing different components of a variable and also the relating of, the components to the whole. Angular or Pie-Diagram: Pie-diagram is an alternative representation of the data set which can be presented in sub-divided and percentage bars or rectangles. Diagrammatic Mode of Presentation: A. Non-Frequency Diagrams: Non-frequency diagrams correspond to the data which are NOT frequency data. 4k watch mins. 2.

Here in this blog, we will share with you the top 7 types of statistics graphs commonly used in statistics. Therefore we should have the proper knowledge of the kinds of statistics graphs available in the world. (iv) Without tabulation, statistical analysis of data is not possible. The best part is that a layman can easily understand the diagrams and pictures as compared to figures. Master Quiz feat. Diagrammatic representation of data has become very much significant in the modern time because of the following points of its merits: (i) They are attractive: Diagrams, per se, are very attractive as they delight the eyes and appeal to the mind of the people in general.Because of this, they are vaguely used in meetings, conferences, fairs, exhibitions, and other public function. Dr. R Jayashree, Asst. Statisticians commonly used these graphs to represent the data graphically. Information Visualization 2017 17: 4 , 316-334 Download Citation.

Diagrams are just supplement to tabulation. For the year 2002, the profit is 5 thousand dollars. Bars i.e. Graphic representation is another way of analysing numerical data. Only a limited set of data can be presented in the form of diagram. We consider Multiple or Grouped Bar diagrams to compare related series. Diagrammatic Presentation of Data Diagrams are an essential operational tool for the purpose of presentation of statistical data. We use Multiple line chart for representing two or more related time series data expressed in the same unit and multiple – axis chart in somewhat similar situations, if the variables are expressed in different units. Construct a pie chart using the angle measurement. Now, plotting all these point and joining them using ruler, we can get the line diagram. Draw a pie chart to represent the above information. Most of the time, the statistics data sets contain massive amounts of values. It is the statistics chart to uncover the potential of the dataset. This graph breaks each value of a quantitative data set into two pieces. Therefore the significant role of statistics is to represent the data in a meaningful way. In this way, anyone can understand the data without in-depth knowledge of statistics. rectangles of equal width and usually of varying lengths are drawn either, We consider Multiple or Grouped Bar diagrams to compare, related series. (2). Diagrammatic Presentation of Data. the sectors of a circle and the whole circle represents the sum of the Diagrammatic Representation of Data Types and Data Manipulations in a Combined Data- and Control-Flow Language. Most of the statistics students are also well aware of exponentials graphs, logarithmic graphs, trigonometric graphs, cartesian graphs, and frequency distributions graphs. Apart from the stuff given above, if you need any other stuff in math, please use our google custom search here. The areas of rectangle are proportional to the frequencies. It exhibits the relation between data, ideas, information and concepts in a diagram. Mostly class-intervals are presented via this mode. However, compared to tabulation, this is less accurate. Data visualization is an interdisciplinary field that deals with the graphic representation of data.It is a particularly efficient way of communicating when the data is numerous as for example a Time Series.From an academic point of view, this representation can be considered as a mapping between the original data (usually numerical) and graphic elements (for example, lines or points in a chart). We are going to consider the following types of diagrams : When the time series exhibit a wide range of fluctuations, we may think of logarithmic or ratio chart where "Log y" and not "y" is plotted against "t". There are three types of bars in this chart i.e., single, stacked, and grouped. (iii) It is a must for diagrammatic representation. There is substan­ tial interest in diagrams and their use in many academic disciplines for the potential benefits they may confer on a wide range of tasks.
