What is a Type 1 error?
- Rejecting the null hypothesis when it is actually true, and you should have accepted it - There is no difference between groups, but you think there is
33
What is a Type 2 error?
- Not rejecting the null hypothesis when it is false, and you should have rejected it - there is a difference
