  • To increase the speed of data collection
  • To make the research process more complicated
  • To ensure that the results are consistent and trustworthy (correct)

    • What does 'reliability' refer to?

  • Consistency and dependability of results (correct)
  • The accuracy of a single result
  • The speed at which a task is completed
