Double bar or divided bar graph is preferred when we want to compare two sets of related data. An officer with a monthly salary of Rs. 7200 plans his budget for a month as given below: Represent this data by a bar graph. This data can be represented by a ..

1. In a simple bar graph, the height of each bar represents the frequency. The thickness has no significance. All bars to have the same thickness. 2. We use double bar graph when we want to compare two things. 3. In the frequency polygon, th..

Summary - In a simple bar graph, the height of each bar represents the frequency. The thickness has no significance. All bars to have the same thickness. We use double bar graph when we want to compare two things. In the pie chart, In the frequency polygon, t..

Facts and figures as such do not catch our attention unless they are presented in an interesting way. Graphical representation of data is one of the most commonly used modes of presentation. Graphs can not only be made attractive, but they are also easy to comprehend and do not take much time to re..
