Maximization of score in Data Interpretation
Major challenges while tackling CAT DI Questions are illusions, relevance and consistency regarding data. The data sets are designed to confuse and mislead. The challenge to crack these types of questions is to swiftly identify, analyze and interpret the data. If you work on the following points, you would be able to improve your score in the data interpretation questions.
1. Calculation speed and sense of approximation: The Data Interpretation section is calculation-intensive. Sometimes the calculations involved in a question are very tough. It is therefore, important for you to get comfortable with calculations. All the relevant tables, squares and cubes should be on your fingertips. Practice well to enhance your calculation speed and accuracy. Try doing calculations in your mind rather than using pencil/pen. Excess use of calculator would also reduce your attempts as you may be tempted to do all the calculations with the help of calculators only, even when it is not necessary. It is understandable in the beginning, but slowly and gradually you will see a remarkable difference in your speed.
2. Careful reading to avoid language traps: It will be unfair to say that Data Interpretation is ONLY about calculations. It is also about logic and reasoning. Sometimes the questions are framed in such a way that you mark an obvious looking answer – which is often wrong! Therefore it is important to work on your reading and comprehending skills. For this, you can start reading business newspapers which have articles that are data-intensive and have graphs & pie-charts etc.
