A measurement is reproducible if the investigation is repeated by another person, or by using different equipment or techniques, and the same results are obtained. N.B. "the same" results implies identical, but in reality "the same" means that random error will still be present in the results. e.g. Raj, Reg and Robin use stopwatches to record the time taken for a pendulum to swing back and forth. Their results are reasonably similar, which means they can feel confident that they are reproducible. By averaging their results, the mean will probably be quite accurate. Raj: 1.27 s
