Major Problems in Using Secondary Data Sources
What are the major problems in using secondary data, such as birth or death certificate data? What, if anything, can the evaluator do about these problems? Research does not always involve the collection of data from the participants. There is a huge amount of data that is being collected through the routine management information system and other surveys or research activities. The existing data can be analyzed to generate a new hypothesis or answer critical research questions. This saves lots of time, money and other resources. Also, data from large sample surveys may be of higher quality and representative of the population.
