In tables, data is arranged in the form of rows and columns. In DI table questions, you are required to read data from table/s, analyze the same and answer the given questions on the basis of the same.
What does a Data Interpretation Table chart represent?
Data Interpretation questions based on tables are common in competitive exams. The boxes of the table consist of different types of information such as marks of a student, income of a company, production of some firm, expenditure on different items and so on. Generally the first row and column of the table denote the titles. The level of questions in tables may be higher or lower as compared to the other form of graphs. This is largely dependent upon the data given in the table and the way questions are framed.
Data Interpretation – Tips
  • Before solving a question, read the information given in the table very carefully as even minute detail may change the question entirely. Understand the instructions carefully to avoid wastage of time while calculating data.
  • Be attentive about the units given in the table and also about those asked in answer options. A mistake in units may result in different or wrong answers.

  • Also pay attention to whether the answer options are given in decimal or percentage. This type of error easily occurs in DI - Tables and is easily avoidable.
  • Try to use approximation technique i.e. if the answer options are wide, then time should not be wasted to calculate the exact figures. But if one of the options is 'none of the above', a close approximation will suffice.
