Data is a set of values of subjects with respect to qualitative or quantitative variables.

Data is measured, collected and reported, and analyzed, whereupon it can be visualized using graphs, images or other analysis tools.

Raw data or unprocessed data is a collection of numbers or characters before it has been “cleaned” and corrected by researchers.

Raw data needs to be corrected to remove outliers or obvious instrument or data entry errors.

Data processing commonly occurs by stages, and the “processed data” from one stage may be considered the “raw data” of the next stage.

Field data is raw data that is collected in an uncontrolled “in situ” environment.

Experimental data is data that is generated within the context of a scientific investigation by observation and recording.

Data has been described as the new oil of the digital economy.
