Data Interpretation Tips
Ø Before starting DI section one should be very comfortable with numbers, calculations, fractions, percentages, averages, ratios. It helps in reducing the time required for solving the questions.
Ø Scan the data briefly to see what it is about, but here do not attempt to analyse it in too much detail before reading a question. Focus on only those aspects of the data that are necessary to answer the question.
Ø Be sure to read all notes related to the data.
Ø When possible, try to make visual comparisons of the data given in a graph and estimate products and quotients rather than perform involved computations. Remember that these questions are to be answered only on the basis of the data given, everyday facts (such as the number of days in a year), and your knowledge of mathematics.
Ø Do not make use of specific information you recall that might relate to the particular situation on which the questions are based unless that information can be derived from the date provided.
Now lets have a look at the types of the DIAGRAMS which are used ind data Interpretations and shall do some problems on them. (Click on the name of the Data Interpretation model for the description and model problems.
