# Thread: Type 1 error and Type 2 Error

1. ## Type 1 error and Type 2 Error

What happens to the type I and type II errors as the sample size becomes larger and larger?

Do you know the definition of a Type I error and a Type II error?

3. ## Re:

type I errors occur when a false occurs, type II errors occur when a false negative occurs. Right?

Pr(Type I error) = Pr(reject H0 | H0 is true).

Pr(Type II error) = Pr(accept H0 | H1 is true).

Think about what happens to these two probabilities as $n_{\text{sample}} \rightarrow n_{\text{population}}$.
