Data Interpretation

In Data interpretation, a large volume of data is organized and is represented into a compact and precise form which is easier to 

interpret than the raw data.

 Students are required to draw conclusions and inferences from a comprehensive data presented 

numerically in these organized forms by means of a table or a graphical image (Graphs, Pie-Chart etc.). It tests speed as well as understanding, analytical and decision making capabilities of the students.

• Ratio

▪1. Read the question carefully: The first and the most important 

step in solving any Data Interpretation question is to read the 

question carefully. You should read all the data that comes with 

the graphs or table in the question. Many a times, the data given 

above/below the graph (additional instructions) turn out to be 

more important than most of the numbers in the graphs.

2. Analyze the data carefully: The next step is to analyze the given 

graph/data carefully. Do not try to see the questions first and find 

out the answers accordingly. You will waste your time following 

that method. Try to understand the graph. Look at the type of data given in each graph, chart, table or pie chart. Look carefully at the 

labels.

3)Don’t worry about too much data: Try to understand the 

question. Sometimes, the question contains lots of data that is 

unrelated and is not required for answering the questions. When 

you look at the question you may get discouraged by the lengthy 

tables or by the amount of information given above/below the 

graphs. But, if you try to understand what the data is about and 

then look at the question, you may find that you only have to use 

part of the data. Hence, it is important that you do not get 

disheartened by the size of the data and skip the question without 

looking closely at it.

4. Learn to skim through data: Some graphs have a lot of data 

associated with them and not all of which is required to solve the 

questions. Skimming through the data and avoiding mess is an 

important part of the process. So, just focus on what is required in 

the question, rather than on all the data at one time.

5. Avoid unnecessary calculations: We have a habit from our 

school days to solve questions in a step by step method. This is a 

very good habit for school exams but a really bad habit when it 

comes to the competitive exams. There are many unnecessary 

calculations that we do while attempting the questions which cost 

us a precious few seconds per question. Sometimes, there are 

many steps that can be skipped but we still do it as we are trained 

to solve in a step by step method. Learn to skip those steps.

Learn to approximate: You do not need to calculate the exact 

answer for every question. Many a times, the options given are far 

enough from each other to give you enough room for approximation. So, instead of finding the accurate answer, try to find an approximate answer. This will give you the correct answer more often than not. If however, the options are close, you will still be able to eliminate 1 or 2 options easily.

7. Pay close attention to the units 

 Sometimes, the questions 

may use a different unit for the question and another unit for the 

data. If you do not pay close attention to the unit, you may be ended up choosing the wrong answer. Always convert the units into the ones which are asked in the question. 

8. Skip questions that need too much calculation:Some questions ask too much from you. They require lots of calculation in order to be solved. These questions are known as the speed-breakers. Such questions are best left alone, at least in the first round of attempt. Once you have finished solving all the easy questions and still have time left for the section, you should attempt these questions. If you try such questions, you will lose your precious time on them and may not be able to attempt some simple questions that may follow.

9. Don’t assume anything: Sometimes there are questions which 

need to find out some data which cannot be calculated even with 

the help of the data given in the graph and the question. Always be alert enough to see whether the data given is enough to answer the question or not and do not go forward with answering the questions based on assumptions. Sometimes, ‘cannot be 

determined’ can also be the correct answer.
