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

  2. CEP 758, Spring 2008 Mokter Hossain Introduction: 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

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

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

  5. CEP 758, Spring 2008 Mokter Hossain Data Vs Information Examples of 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.

  6. CEP 758, Spring 2008 Mokter Hossain Data Vs Information Characteristics of Data: • Data are the raw materials of information • Data is a distinct piece of information • Data must be disorganized or unprocessed

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

  8. CEP 758, Spring 2008 Mokter Hossain Data Vs Information Examples of 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.

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

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

  11. CEP 758, Spring 2008 Mokter Hossain 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.

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

  13. CEP 758, Spring 2008 Mokter Hossain Data Vs 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
