Diagrammatic Presentation of Data is a technique of presenting numeric data through pictograms, bar diagrams, and pie diagrams etc. It is the most attractive and appealing way to represent statistical data. Diagrams help in visual comparison, and they have a bird's eye view. Statistics perform an important function by presenting a complex mass of data in a simple way that makes it easier to understand. Classification and tabulation are two techniques for presenting data in an understandable form. However, as the volume of data increases, it becomes increasingly inconvenient to understand, even after classification and tabulation. Thus, data is presented in the form of diagrams and graphs to enable the comparison of various situations and to comprehend distinct patterns in the data at a glance.
Students of grade XI Commerce and Humanities streams were asked to make PowerPoint Presentations on the varied forms of Diagrammatic Presentation, such as simple bar diagrams, multiple bar diagrams, Sub-divided bar diagrams, Percentage bar diagrams, Broken-Scale bar diagrams, and Deviation bar diagrams. Students were excited to present the data gathered and explained the various forms of Geometric Diagrams with examples.
This activity helped the students to tabulate the complex data easily by showcasing it in the form of different diagrams and helps a layperson to understand the data presented. Students were able to co-relate the data with the help of theoretical and practical application.
