Probability type 1 error

Webb28 sep. 2024 · Type I error is an omission that happens when a null hypothesis is reprobated during hypothesis testing. This is when it is indeed precise or positive and should not have been initially disapproved. So if a null hypothesis is erroneously rejected when it is positive, it is called a Type I error.

WebbA Type I error (or Type 1 ), is the incorrect rejection of a true null hypothesis. The alpha symbol, α, is usually used to denote a Type I error. A Type II error (sometimes called a Type 2 error) is the failure to reject a false null hypothesis. The probability of a type II error is denoted by the beta symbol β.

WebbThe power of a study is defined as 1 – and is the probability of rejecting the null hypothesis when it is false. The most common reason for type II errors is that the study is too small.
