Data Analysis & Interpretation

Data Analysis & Interpretation

Data Interpretation has always played a great role in selection for SBI PO. In Phase One exam also SBI has asked for Data Interpretation Questions in Quantitative Sections. SBI Online Phase 2 Exams will be having a complete 60 marks section devoted to Data Interpretation. 

Many Student face difficulty in tackling with DI section while some others are very efficient in Data Interpretation.

The best part of Data Interpretation is that this section can be mastered in very less time compared to other subjects such as Quantitative Section and English or General Awareness.

Now Let us come to the most Important Thing.

" Demystifying Data Interpretation ”

Look anyone can solve DI question, if there is no time limit given. But in Exam we are required to solve the question in limited Time.

Few Necessary Skills which are required for Mastering DI are Listed as below:

1.Read the data very carefully. Even the minutest word must not be overlooked since many a times even single word/group of words could become critical.

2.If there are more than one graphs/charts/tables, understand the relationship between them clearly before you proceed to solve the questioned asked.

3.Answer only the questions asked. Do not answer/calculate things which have not been asked for.

4.Be careful to use proper units and beware of charts and tables with non-uniform units.

5.Avoid simple calculation mistake and revise your answer at least once before moving to next question.

Tips to reduce calculation time

In DI most of the questions are usually based on percentage increase and decrease, ratios and averages. A simple trick for solving data interpretation problems quickly is:

• Learn tables till 20.
• learn fractions till 1/20 to improve your speed
• Waste little time in finding averages: Here if you have to find averages for sales in branches B1 to B6 for the year 2014, use this shortcut:

                          What you usually do: [80+75+95+85+75+70]/6

                               Instead: 70 + [10+5+25+15+5]/6=70+ [60/6]= 80

      With this technique, you will reduce calculation time and are also bound to make fewer mistakes.
