Difference between Primary and Secondary data

Primary Data

  • Needs more funds.
  • Investigating Agency collects the data.
  • Requires longer time for collection.
  • More reliable and suitable to the enquiry because the investigator himself collects it.
  • Requires elaborate organisation.
  • No extra precautions are required.

Secondary Data

  • Needs comparatively less funds.
  • Some other investigating agency collects it for its own use.
  • Requires less time for collection.
  • Less reliable and suitable as someone else has done that job of collection which may not serve the purpose.
  • No need of any organizational set up.
  • Secondary data need more care and attention.
