Family-wise error

WebThe family-wise error is meant to capture the overall situation in terms of measuring the likelihood of making a mistake if we consider many tests, each with some chance of making their own mistake, and focus on how often we make at least one error when we do many tests. A quick probability calculation shows the magnitude of the problem. WebIn statistics, the multiple comparisons, multiplicity or multiple testing problem occurs when one considers a set of statistical inferences simultaneously or infers a subset of parameters selected based on the observed values.. The more inferences are made, the more likely erroneous inferences become. Several statistical techniques have been developed to …

WebJan 14, 2024 · The experiment-wise error rate represents the probability of a type I error (false positive) over the total family of comparisons. Our ANOVA example has four groups, which produces six comparisons and a family-wise error rate of 0.26. If you increase the groups to five, the error rate jumps to 40%!
