http://www.isixsigma.com/dictionary/Alpha_Risk-186.htm

Alpha risk is defined as the risk of rejecting the Null hypothesis when in fact it is true.

Synonymous with: Type I error, Producers Risk

In other words, stating a difference exists where actually there is none. Alpha risk is stated in terms of probability (such as 0.05 or 5%).

The value (1-alpha) corresponds to the confidence level of a statistical test, so a level of significance alpha = 0.05 corresponds to a 95% confidence level.

Excellent. Just what I needed. Great link. Thank you.

agree Sylvia Smith : I believe alpha is the symbol before the ">0,05" in Karen's post, but it could just be something strange with my computer
