Data sources

This section talks about the various sources of data available to you and when each is most appropriate to use.

3. Evaluation of secondary data

It is very rare for the secondary data available to exactly match your research problem. Although secondary data offer a lot of advantages (time and cost savings, enriching primary data), there are some problems associated with them. To evaluate their usefulness, you should ask yourself some questions, such as:

  • What was the purpose of the study for which the data were collected?
  • Who collected the data and published the information?
  • What information was collected?
  • How was the information obtained?
  • How consistent is the information across sources?
