MBA aspirants who are appearing in CMAT First Test  being conducted from 25th September to 29th September 2014  may find following useful for practice:
 
Data Interpretation is a vital section of almost all the competitive exams, especially MBA entrance exams. They have a dedicated section for questions base on Data Interpretation. 
 
The DI section tries to test the aspirants’ skill of analyzing a set of data to find out some information that may or may not be provided directly in the question but has to be calculated or estimated using the given data.
 
It basically tests you as a candidate on the parameters of interpretation skills, accuracy, speed and ability to crunch numbers. 
 
Here, we are stating few very basic things related to DI that will help you in the preparation of this section as the DI questions of CMAT 2013, like previous years, will be lengthy yet scoring. 
 
A) Data and Information
 
In DI section, questions are presented in forms of tables or paragraphs that have data values such as measurements, observations or just descriptions in numbers or words, etc. You need to analyze what all information you can infer from the presented set of data. 
 
These data could be in arranged, systematic or unorganized form as well and as an MBA aspirant, you are supposed to analyze the given data and understand the information it wants to deliver. Your understanding and analytical skills is tested by framing direct as well as indirect questions from the given data. 
 
B) Speed and Accuracy
 
You need to practise small calculations like additions, subtractions, roots and percentages with mental methods that provide shortcuts for calculations. These small calculations need to be done through mental calculations as you need not calculate the exact figures in each and every step. 
 
That is why, DI calls for speedy calculation skills but only for correct estimation and not exact answers. The correct answer can be judged from the provided options. So, please don’t waste time calculating till the last digit; rather apply the “rule-out” method as you proceed with your calculation.
 
However, with speed you also need to concentrate on accuracy. So, be prepared to crunch numbers like peanuts. You need to be on your toes to calculate a certain percentages and roots very quickly and that also with ultimate accuracy as any one wrong digit can make your complete set of solution wrong. 
 
C) Time Constrain
 
You need to be rapid with calculations as you have to keep a check on time as well. You are supposed to analyze the given information and come out with accurate solution but in limited time frame. 
 
If you practise enough and start playing with set of numbers, you will be able to solve as many questions as you can, with utmost accuracy, in limited time.
