What is Data?
According to the Oxford “Data is distinct pieces of information, usually formatted in a special way”. Data can be measured, collected, reported, and analyzed, whereupon it is often visualized using graphs, images, or other analysis tools. Raw data (“unprocessed data”) may be a collection of numbers or characters before it’s been “cleaned” and corrected by researchers. It must be corrected so that we can remove outliers, instruments, or data entry errors. Data processing commonly occurs in stages, and therefore the “processed data” from one stage could also be considered the “raw data” of subsequent stages. Field data is data that’s collected in an uncontrolled “in situ” environment. Experimental data is the data that is generated within the observation of scientific investigations. Data can be generated by:
- Humans
- Machines
- Human-Machine combines.
It can often generated anywhere where any information is generated and stored in structured or unstructured formats.
