| euniceyew | how to know is type 1? any calculation required? can anyone explain further? |
| SuperKnight | You know its type 1 because a decision to reject the null hypothesis has been made, the other (Type II error) occurs when you fail to reject the null hypothesis. Either decision, rejecting or failing to reject the null hypothesis will always leave you open to one of the errors. |
| bhaynes | If we ever reject the Null, then there is a possible Type I error. Not rejecting = possible Type II error |
You have a wonderful website and definitely should take some credit for your members' outstanding grades.
