What is the relation between information and data?

In a sentence: data is raw numbers, while information is organized data.

Explanation:

Data is a series of numbers or facts.  A data set is a collection of data that are related (for examples all the students result in your last math exam).  But it's not organized by itself... and rarely mean anything when looked at it in a raw manner.

To make sense of a data collection, you have to analyze it, calculate the mean or median of the data set for example... this is a treatment that has to be done to a data set to give it significance.. after such analysis, the result you have (mean, median, etc..) is a piece of information devired from the data.
