But it is not exact. Although the increase of the test number raises the probability of the Type Ⅰ error, it does not demonstrate the proposition. We should calculate the real probability of the Type Ⅰ error with P-value not the α-value from each test.展开更多

Although the increase of the test number raises the probability of the Type Ⅰ error, it does not demonstrate the proposition.
