Revise: Data Evaluation and Drawing ConclusionsNeither repeatability nor reproducibility guarantees accuracy. A faulty instrument can give the same wrong reading repeatedly, while different investigators may share a method containing the same systematic bias.
Obtaining similar results when an investigation is carried out again by another person or using different equipment or methods.
For every suggested improvement, explain which problem it addresses and how it improves accuracy, precision, repeatability or reproducibility.
When asked how a theory changes, give a chain: new evidence is obtained, scientists assess its quality and reproducibility, then the explanation is retained, modified or replaced according to how well it accounts for the evidence.
