There are a number of sampling techniques available to researchers and the decision as to which to choose will depend on a number of factors.

Identify as many factors as possible which might affect the choice of sampling technique.

Suggestions:

  • Positivists might be looking for a sample which is representative of the target population
  • The group to be studied may be difficult to access
  • Availability
  • Convenience
  • The timescale of the research may be restricted
  • There may not be a sampling frame available
  • The group that forms the target population to be studied may be very large – too large to research them all.
  • The extent to which the researcher wants to make generalisations about their findings to the target population.
