Detailed UGC NET Data Interpretation Notes 2021

UGC Data Interpretation Notes cover the topics as given below.

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

Types Data set in UGC NET Exam

You should know that the Data can be written or represented in 4 Forms. These are,

• 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.

Important Information Related To UGC Data Interpretation Questions

• The questions will not only come from quantitative skills but also relative, comparative and analytical ability.
• Mainly you have to find a relationship between the two tables or graphs before attempting the questions.
• You will find the Data Interpretation questions are based on the 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 newspapers to present a set of numerical facts.

Other Important Sections

Percentage and Ratio applications: These two chapters from Quantitative Aptitude has a certain role to be played in DI calculation.

• 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 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 the 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 360 degrees.
