Unit 6: Quanitative research

  • Do the authors totally ramdomise the sample to make it more representative of the population? How do they do this?
  • This reduces bias and therefore makes the findings more generalisable.
  • If a sample of convenience is used, then to reduce bias it needs to be large enough to be representative.
  • Sometimes a large convenient sample may be randomised into smaller groups.
  • Types of sampling are detailed in the previous section.
  • Did they use statistical calculations (power calculations) to determine how many people were needed in the sample to make the findings generalisable.
  • Large numbers required
