WebbSince these researchers test hundreds of thousands or even millions of separate genome locations, Type I Errors would be expected to occur far too frequently if they used a 95% or 99% interval. After all, 5% of 1,000,000 is 50,000 and 1% of 1,000,000 is 10,000. Next: Statistics Case Studies: Decision Errors References WebbIn fact, it may be possible to increase the overall power of a trial by carrying out tests on multiple outcomes without increasing the probability of making at least one type I error when all null hypotheses are true. We examine two types of problems to illustrate this.
