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 =
