1. WELCOME TO MY PRESENTATION ON 1 CEP 758, Spring 2008 Mokter Hossain Data Vs Information Instructed By: LaMont Johnson, PhD Professor, Dept of CEP University of Nevada, Reno

2. 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: 2 CEP 758, Spring 2008 Mokter Hossain

3.  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: 3 CEP 758, Spring 2008 Mokter Hossain Data Vs Information

4.  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: 4 CEP 758, Spring 2008 Mokter Hossain Data Vs Information

5.  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: 5 CEP 758, Spring 2008 Mokter Hossain Data Vs Information

6.  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 2008 Mokter Hossain Data Vs Information

7.  Information is the simplified form of data.  When the data is processed or organized it becomes information. Information: 7 CEP 758, Spring 2008 Mokter Hossain Data Vs Information

8.  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: 8 CEP 758, Spring 2008 Mokter Hossain Data Vs Information

9.  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: 9 CEP 758, Spring 2008 Mokter Hossain Data Vs Information

10. 10 CEP 758, Spring 2008 Mokter Hossain Data Vs Information by a Chart: Data Vs Information

11. 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. 11 CEP 758, Spring 2008 Mokter Hossain Data Vs Information

12. 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. 12 CEP 758, Spring 2008 Mokter Hossain Data Vs Information

13. 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 13 CEP 758, Spring 2008 Mokter Hossain Data Vs Information
