Replication vs Repetition (the difference)

Repetition involves consecutive runs of the same factor-level combination within a single experimental session, whereas replication involves non-consecutive runs of the entire experimental design in different experimental setups.

Example: If you are studying the impact of temperature and pressure on the yield of a chemical reaction:

  • Repetition: You would run the experiment at 25°C and 1 atm pressure multiple times consecutively within the same session.
  • Replication: You would run the entire experimental design (which might include various combinations of temperature and pressure) multiple times but in different sessions or setups.
