Juan conducted an experiment and asked Catherine to replicate it. Juan’s values are 16, 15, 15, 16, and 15. Catherine’s values are 16, 14, 16, 15, and 15. Which is one correct description of Catherine’s data when compared to Juan’s data?

Catherine’s measurements are close to Juan’s results: both sets are centered around 15–16, and their averages are 15.2 and 15.4. This means her results are accurate compared with Juan’s, even though the individual values are not identical. “Falsified” and “invalid” do not describe this small difference between the data sets.
