In caselets data are given in the form of paragraph. No charts/graphs are provided with the data. Caselets vary considerably in length, in the amount of information contained, in different sentences and paragraph. While reading a caselets it s always advisable to underline the important fact and figures and if necessary make your own table/chart/graphs for solving the questions.

In CAT Caselets can be asked either/both in Quants and Data Interpretation section and it s similar to the Reading Comprehension part in English Usage section. The best way to mastery caslets is to practice

A pie chart is a circle graph divided into pieces, each displaying the size of some related piece of information. Pie charts are used to display the sizes of parts that make up some whole. In a pie chart, the arc length of each sector (and consequently its central angle and area), is proportional to the quantity it represents. Together, the sectors create a full disk

Bar graphs are used to display data in a similar way to line graphs. However, rather than using a point on a plane to define a value, a bar graph uses a horizontal or vertical rectangular bar that levels off at the appropriate level.

There are many characteristics of bar graphs that make them useful. Some of these are that: They make comparisons between different variables very easy to see. They clearly show trends in data, meaning that they show how one variable is affected as the other rises or falls.

In first DI chapter we discussed about Tabular Data Representation. Here we 'll try to present similar set of data in a graph.
