A type 1 error occurs when you wrongly reject the null hypothesis (i.e. you think you found a significant effect when there really isn't one). A type 2 error occurs when you wrongly fail to reject the null hypothesis (i.e. you miss a significant effect that is really there). video https://cdn.kastatic.org/googleusercontent/Okl0qDRVunIQZp3ZADIl-ExCR38MYhv7apTl6dIf0ykIzYWu0WeBGLysl9lblpx6Jboh_L-tFwA1jiZyAv5iCz4 Introduction to Type I and Type II errors Both type 1 and type 2 errors are mistakes made when testing a hypothesis.
