How to Solve Questions Based on Data Interpretation UGC NET EXAM

Myth:  There are Students who think  “I will solve at least 10/10 Question from DI and Maths based Reasoning”; But due to lack of Practice/Formula & Proper Guide about how to solve them in given time they waste ample amount in the calculation and solving these Question.

DI based question asked in CBSE UGC NET Exam is not as much as tough which is asked in Bank PO/SO exams. The difficulty is also not as asked in MBA entrance exam but it is somewhat of the mediocre level (Not Too Easy; Nor Too Tough !)

Data Interpretation Paper Pattern in UGC NET exam: How to prepare?

In  UGC NET exam, Based on Last 10 Year Papers we see there will be (5-6) Questions Based on DI. Most of the cases, they will be based on Table &  PI/Bar Chart.

Let’s have look on the number of question asked in last 8 years.

Below is the list of the name of the exam along with no of the question asked in the UGC NET EXAM.

  • Dec 2018 (Mostly 5 MCQ Question based on Questions based on Basic math operation)
  • July 2018(5 MCQ Based on production, exports and per capita consumption of rice- Again Basic Math Operation)
  • Nov 2017 (5 MCQ Based on Number of registered vehicles in India and India’s population- Basic Math Operation)
  • January 2017 (6 MCQs  Based on  Two Data Tables)
  • August 2016 (6 MCQs  Based on  Two Data Tables) (Re-test)
  • July 2016 (6 MCQs Based on Two tables. Questions based on Basic math operation)
  • December 2015 (6 MCQs  Based on Tabular data on  Population Growth)
  • June 2015 (6 MCQs Based on Tabular data. questions are based on avg & %)
  • December 2014 (6 MCQs based on CO2 emissions. Mostly on % growth and relative changes)
  • June 2014 (6 MCQs on Irrigation Data Interpretation. Mostly again based on % )
  • December 2013 (6 MCQs on  Foreign Tourist Arrivals Data Interpretation. Most of the Questions are based on relative comparisons. )
  • September 2013 (4 MCQs on Data production of energy Interpretation) (Re-test)
  • June 2013 (6 MCQs on  Major Horticulture Crops Tabular Data Interpretation)
  • December 2012 (6th MCQs on Government Expenditures on Social Services Data Interpretation)
  • June 2012 (2 MCQs on based on total electricity generation PI Chart Data Interpretation)
  • December 2011 (2 MCQs on based total CO2 emissions PI Chart Data Interpretation)
  • June 2011 (3 Question Based on Numerical Values  Data Interpretation)
  • December 2010 (5 MCQs based on the production of electronic items Data Interpretation)
  • June 2010 (3 MCQs  Based on Bar Chart  Data Interpretation)
The Significant change we see in the paper pattern over years is that previously there is 5-6 Question based out of 1 Dataset. However, now we see 3-3 Question on two type of data set. Also in the last few year questions were asked mostly based on tabular data. This is a little tricky as this will be time-consuming for candidates to analyse two datasets and solve 3 question based on each data set.

By the way below  is the Official Syllabus  for Data Interpretation Topics for UGC NET EXAM

  • Sources, Acquisition and Interpretation of Data.
  • Quantitative and Qualitative Data.
  • Graphical Representation and Mapping of Data.

Data Interpretation Tricks for UGC NET exam: How to prepare well?

We will also discuss in details how to solve toughest DI …..and we will solve some practice set after reading the article.

I have compiled from various sites….a good study material for you in one place.

Hope you will enjoy it….First, we will discuss various tips and tricks for solving DI/Data interpretation….So get ready for DI solving tricks and tips.

What kind of Data set can we expect in Exam?

Data can be written or represented in 4 Forms(Data can be presented either through words as in case-lets or through pictorial methods. Out of all the types of pictorial charts, table, bar chart, pie chart and line chart are most frequently used types)

  • Numerical:- Data in the numerical form
  • Table Form:- Data in Tabular Form
  • Mixed form:- Data in Mix Form
  • Graphical form Like Line, Bar graph, PI Chart etc.

Tricks to Crack Data Interpretation

 

  • The aim is to test not only quantitative skill but also relative, comparative and analytical
    ability.
  • The crux of the matter is to find a relationship between the two tables or graphs before attempting the questions.
  • Data Interpretation questions are based on information given in tables and graphs. These questions test your ability to interpret the information presented and to select the appropriate data for answering a question
  • Get a general picture of the information before reading the question.
  • Avoid lengthy calculations generally, data interpretation questions do not require to do extensive calculations and computations. Most questions simply require reading the data correctly and carefully.
  • Breakdown lengthy questions into smaller parts and eliminate impossible choices.
  • Answer the questions asked and not what you think the questions should be.
  • Tables are often used in reports, magazines and newspaper to present a set of numerical facts.

FEW IMPORTANT AREAS

Percentage and Ratio applications: These two chapters from Quantitative Aptitude has a certain role to be played in DI calculation. This has been seen most of the question in UGC NET exam are based on Percentage and Average Calculation. A ratio is another important topic to care about.

  • Master your Percentage, Ratio, Profit and Loss, Average, Interest Calculations
  • You should Master your two-digit addition which will enhance your calculation speed
  • Some other necessary things are learned multiplication tricks for three/four digits, Square, Cube.
  • Avoid Unnecessary Calculation

Approximation techniques: A very large number of these questions check your ability to compare or calculate fractions and percentages. If you sit down to actually calculate the answer, you would end up spending more time than required. Here are a few ideas that you can use for approximation.

  • Learn the concept of Approximations and Estimations. These are very important to solve DI questions very fast.
  • When trying to calculate (approximate) a fraction p/q, add a value to the denominator and a corresponding value to the numerator before calculating (approximating).
  • If the percentage growth rate is r for a period of t years, the overall growth rate is approximate: rt + t * (t-1) * r2 / 2. Follow RS Aggrawal Book

Calculation Techniques specific to the data sets: There are calculation techniques especially in case of Pie Chart, Line Chart and Bar chart that one should know to reduce the calculation time.

Pie Chart is a circular form of Data representation. In this, the circle is divided into sectors either percentwise or degree-wise. In the per cent-wise division, the total area of the chart is taken to be 100% and in degrees division, the total area of the chart is taken to be 360o.

Don’t use calculators while Practice:

Solve questions in the order in which they appear:

It is usually seen that the answer to the first question is useful in solving the next question. So it is advisable that you solve the questions in the order in which they appear.

Also if you make mistakes while calculating the first question, you will most probably make mistakes in the subsequent questions. So be double sure of your answers.
