Data interpretation is gaining a lot of importance because of the ever-increasing use and collection of data. Data interpretation can be defined as a process where data is analyzed well using various sets of methods or techniques and then arriving upon meaning, inference, or conclusion.

The data analysts use the data from various sources, analyze, and then present it in an appropriate manner, which can be easily understood. So, being able to interpret the data is a prerequisite. It comprises a fair weightage for various aptitude tests or entrance exams for banks such as SBI PO, Clerk role for the bank, IBPS RRB Clerk, RBI Grade A, B, NABARD Grade A & B, LIC AAO, etc. The Data Interpretation notes for Bank PO is as follows.  

Data Interpretation Topics for Bank Exams



Tabular Data

Tables are used to present numerical data. It is the easiest and accurate way of presenting the data. We can understand the information quickly by having a glance over it. 

Bar Graphs

A bar graph can have horizontal or vertical bars. We can compare either the same or different quantities at different times.

Cumulative Graph

Thee bar’s height or the line is divided up proportionally among various quantities presented in a graph, which may be in percentage or absolute numbers.

Line Graphs

They are used to show how a quantity changes continuously. The pattern of the line is observed. 

Pie Charts

They are used to show the share of the various sectors in the total.

Data Interpretation pie chart formula:

Sector angle= Class frequency/ Total Frequency*360 ̊.


Many times, a combination of two similar or, in rare cases, different graphs or charts are used to present the data and analyse it.

Data sufficiency

It means whether the given set of data and statements are sufficient enough to answer the questions that have been asked or not.
