Can you add additional testing on the same subject to the dataset, particularly when it is hard to find study subjects?

BACK TO FAQs

In most studies, you should avoid multiple testing of the same subject because it may skew performance statistics and underestimate standard deviations. When multiple testing is done, you should explain why it is necessary and choose methods of statistical analysis that allow adjustment for within-subject correlation. It is appropriate to conduct repeated testing of the same sample to evaluate test reproducibility, such as the ability of the test to yield the same or similar readings when expected.
