Data Vs Information

Data Vs Information

We frequently use the terms data and information

Generally, data and information are synonymic

But there is a clear distinction between these

Basically, data and information are in plural form

But they might be used in singular form too

Introduction:

As we may not have clear idea about data and

information

So we may do mistake in using the terms data and

information

After completion of this tiny lecture, you will have a

clear understanding on data and information.

Objective:

CEP 758, Spring 2008Mokter Hossain Data Vs Information

Data is the name or measure of an entity, thing or item

Data may relate to reality, or to fiction

Real data may be characters, numbers, or images;

Unreal data may be a fictional movie

Data:

Height of a man, suppose 65 inches, is a data;

His name, suppose Jack, is a data;

His weight, suppose 150 lbs is a data;

His color, suppose white is a data; and so on.

Examples of Data:

Data are the raw materials of information

Data is a distinct piece of information

Data must be disorganized or unprocessed

Characteristics of Data:

6

CEP 758, Spring 2008Mokter Hossain Data Vs Information

Information is the simplified form of data.

When the data is processed or organized it becomes

information.

Information:

CEP 758, Spring 2008Mokter Hossain Data Vs Information

The average height or weight of several people,

suppose 62 inch, is an information;

The average weight of the class, suppose 130 lbs, is

an information; and so on.

Examples of Information:

Information is the resultant version of some data.

Information always be processed or organized

Information is the context in which data is taken.

Characteristics of Information:

Data Vs Information by a Chart:

Data Vs Information

Data Vs Information by a Practical Example:

Suppose, in your first, second, third and fourth year

GPAs are: 3.0, 3.5, 3.5, and 4.0

Then so the CGPA is say something like: 3.5

Here, the individual GPAs are data

And then the finally calculated CGPA is information.

Data Vs Information by Another Example:

Suppose, in your first year , you got individual GPs in

four classes you took as: 3.0, 3.5, 3.5, and 4.0

Then your average grade = (3.0+3.5+3.5+4.0)/4 = 3.5.

Here, the individual GPs you got are data,

And the average grade that is calculated is information.

Just Remember:

Positions of data and information are not always fixed

They change themselves due to change of time or

situation

Just remember that, data is the primary or intermediate

version of information
