Data are raw facts that must be processed, organized and interpreted to become meaningful information.
Data
This refers to raw or unprocessed facts or statistics. Data may either be quantitative-describing something by numbers or quantitative-describing by words. The test scores that a student earns are data.
Information
Data that has already been processed, organized, and interpreted to mean something and contribute value. Information is contextual as well as meaningful. For example, the average class score is an information gathered through the data presented by the student's test score.
Knowledge
The aggregation of past experience and insight that informs how a person perceives and assigns meaning to information. Knowledge is unique to the individual and comprises other elements like experience and intuition.
