![]() ![]() A test must be both credible and valid to be considered reliable. While reliability is essential, it is not adequate on its own. Thus, an Olympic measuring device must be consistent from one race or throw to the next and from one competition to the next. It might even be the difference between an athlete setting a new record and failing to qualify for an event. ![]() However, for an Olympic event like the discus throw, the tiniest change in a measurement instrument such as a measuring tape, the clock, or any other gadget, may make the difference between silver and gold medals. Conventional rulers and their degree of precision may be sufficient for the majority of individuals. ![]() The reliability of measurement equipment is an important aspect during Olympics track and field sports. Aside from having huge relevance in research, reliability is also critical in many parts of our lives, such as industry, health, and sports. Researchers may be unable to draw conclusions, construct hypotheses, or make claims about the generalizability of their study if the methods used by researchers are inconsistent or unreliable. If a test fails to generate the same results, it is said to be “unreliable”. In simpler terms, when the same sample is subjected to the same test under the same conditions, the same results should be obtained. Reliability is the degree to which an investigation, analysis, or procedure produces the same or similar results each time it is repeated. ![]()
