Web統計学において、ファミリーワイズエラー率（ファミリーワイズエラーりつ、、略称: FWER）は、多重仮説検定を行う際に、全ての仮説の中で少なくとも1つの正しい帰無仮説が誤って棄却されてしまう（第一種過誤）確率である。ファミリーは帰無仮説の集合（帰無仮説族）のことであり、ファミリーワイズは「帰無仮説の集合ごとの」といった意 … WebSo, if we see one or more t values above 2.42 in this family of tests, this is not good evidence against the family-wise null hypothesis, which is that all these values have been drawn from a null distribution. We need to ﬁnd a new threshold, such that, in a family of 1000 t statistic values, there is a 1%

Suppose we have a number m of null hypotheses, denoted by: H 1, H 2, ..., H m. Using a statistical test, we reject the null hypothesis if the test is declared significant.We do not reject the null hypothesis if the test is non-significant.
