Data Interpretation is an activity in which one draws conclusion about the data available for analysis. Before attempting to explore data interpretation , let us dwell upon the following facts.

What is data ?

Data is a collection of related facts , figures , information etc. Whenever any data is given always understand the unit of data and scale factor etc. used while reporting the data.

Representation of Data

Next we consider methods to represent data

Tabular Representation of Data

In the method data represented in horizontal rows and vertical column for example let us consider the yearly balance sheet of company ABC.

 Year Revenue (Rs Crore) Operating Cost (Rs Crore) Profit (Rs crore) Sales (Rs crore) 2000 1000 200 300 1200 2001 1200 300 325 1500 2002 1100 250 225 1400 2003 1300 300 425 1500

In the above table each column represents the value for the corresponding variable across the years.

Bar Charts

Bar charts are most suitable when data is to be presented in a format so that comparison is easier to make , Let us consider the total cash reserve of a company aver the years.

Pie Charts

Pie charts are used generally to show the distribution of whole into sub- components. Let us consider the monthly expression of a family.

Rent – 20%

Food – 15%

Entertainment – 10%

Saving – 25%

Mobile phone bill – 30%

total income – 100%

In a pie chart , a circle is divided into sectors, where the angle of the sector is proportional to the value of the sub component . Total expense of 100% is equal to the angel subtended by the circle that is

Sector angle for Rent =

Sector angle for Food =

Sector angel for Entertainment =

Sector angle or Saving =

Sector angle for Mobile phone bill =
