For many years, researchers have conducted studies for clients in business, education and medicine. These researchers have collected data with instruments that would provide them valuable information on which they could base informed conclusions. The research studies were carried out with proven models and the data was collected with valid instruments in controlled conditions to ensure that the conclusions were worthwhile and helpful.
In this age of technology, electronic data collection is used to replace methods that were previously used by the researchers. Electronic data collection should be based on sound principles so it provides valid, accurate information to the researchers.
