Data Interpretation is an extension of Mathematical skill and accuracy that draw conclusions and inferences from a comprehensive data presented numerically in tabular form using an illustration, viz. Graphs, Pie charts, etc. In other words, the act of organising and interpreting data to get meaningful information is Data Interpretation.
Data Interpretation aims to test not only quantitative skill but also relative, comparative, and analytical ability.

- Before solving the questions of Data Interpretation, you must know the different types of representation of data and the basic mathematical calculation.
- Data Interpretation is an estimation of results based on some data in tabular as well as graphical form.
- The questions are based on the information given in tables and graphs. You have to interpret the information presented and to select the appropriate data for answering the questions.
- Observe a general picture of the information before reading the question.
- Read the given titles carefully and try to understand its nature.
- The questions of data interpretation do not require to do extensive calculations and computations. Most questions simply require reading the data correctly and carefully and putting them to use directly with common sense.
- Be careful while dealing with units.
- To make reading easier, and to avoid errors, observe graphs keeping them straight.
Since one of the major benefits of graphs and tables is that they present data in a form that enables you to readily make comparisons, use this visual attribute of graphs and tables to help you answer the questions. Where possible, use your eyes instead of your computational skills.

Example: In the following bar graph, it shows the number of tickets sold by six students A, B. C, D, E, and F during a fair. Observe the graph and answer questions based on it.
Q 1: Total number of tickets sold by A, B and C is:
Ans: (b) From the graph given in the question:
Tickets sold by A=16
Tickets sold by B= 8
Tickets sold by C = 20
Hence, the total number of tickets sold by A, B and C = 16 + 8 + 20 = 44
Q 2: The least number of tickets were sold by
Ans: (d) From the graph given in the question: Least number of tickets were sold by D. He sold 7 tickets.
Q 3: Total number of tickets sold by D, E and F is:
Ans: (c) From the graph given in the question: Ticket sold by D = 7 Ticket sold by E = 24 Ticket sold by F = 14 Thus, the required answer is = 7 + 24 + 14 = 45.
Example: Study the following table and answer the questions given below it.
1: Which of the following units shows continuous increase in production of sugar over months?
a) B b) A c) C d) D
2: In the case of Unit E, in which of the following pairs of months the production of sugar was equal?
a) June & July b) April & June c) July & August d) April & May
3: In the month of June, how many units have a share of more than 25% of the total production of sugar?
a) one b) Three c) Two d) Four
Q 4: What was approximate percentage decrease in sugar production of unit B in June as compared to April?
a) 8 % b) 1 0% c) 1 5% d) 1 8%
Note: To solve the question of DI, you need some basic mathematical calculations. If you don’t have interest or not comfortable to simple calculation like ratio, averages, percentage etc., then keep away yourself from this section.
If you think that you can improve basic mathematical skills then practice more and more before appearing in the exam. Otherwise, you will kill your time and spoil Paper 1 by trying to solve this section. Be careful.
