Henry and Alex both completed the same experiment and got similar results. Henry ran his experiment 5 times and took an average value, while Alex only ran his experiment once.Which statement best describes their experiments?

Replication occurs when a different person carries out the same experiment, so Henry’s and Alex’s experiments replicate each other. Repetition means running the experiment multiple times; Henry repeated his experiment five times, but Alex ran it only once. Therefore, both experiments involved replication, but only Henry’s involved repetition.
