Rule Of Three (statistics)
In statistical analysis, the rule of three states that if a certain event did not occur in a sample with Design of experiments, subjects, the interval from 0 to 3/ is a 95% confidence interval for the rate of occurrences in the population (statistics), population. When is greater than 30, this is a good approximation of results from more sensitive tests. For example, a pain-relief drug is tested on 1500 Human subjects research, human subjects, and no adverse event is recorded. From the rule of three, it can be concluded with 95% confidence that fewer than 1 person in 500 (or 3/1500) will experience an adverse event. By symmetry, for only successes, the 95% confidence interval is . The rule is useful in the interpretation of clinical trials generally, particularly in Phases of clinical research#Phase II, phase II and phase III where often there are limitations in duration or statistical power. The rule of three applies well beyond medical research, to any trial done t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
