With the secondary research method you don’t know how accurate it is or whether it is biased or not, although the secondary research method could have been usedby a person who may have better facilities than you to produce more accurate results whereas in the primary research method, you may not have many facilities at your disposal. 1. 6Describe how to search for relevant data sources There are many ways of searching for relevant data sources such as the internet, books, previous reports and speaking to the team.
