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.

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
