Which of the following is a reason why the results of a data analysis should be reproducible, as emphasised in the data analysis process?

Reproducibility lets others repeat and check the analysis by using the recorded data sources, code and assumptions. It supports review and trust, but it does not guarantee the conclusions are correct or remove the need for cleaning.

  2. BIt removes the need for data cleaning
  3. CIt allows others to repeat the work and check it, for example by recording the data sources, code and assumptionsCorrect
  4. DIt ensures the sample size is large enough
  5. It makes the use of random numbers impossible
