Alpha Risk

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.

About iSixSigma Military

The purpose of this iSixSigma Military channel is to document the transformation of the United States Armed Services through the use of Lean Six Sigma and related process improvement methodologies.

Ronald E. Rezek, special assistant to the acting secretary of the Army, has said the goal of the Army's Lean Six Sigma deployment is to "make the business side of the Army as efficient as the war-fighting side is effective." Leaders of the other armed services echo that sentiment and transformation objective.

This portal will serve as a central community for everyone associated with the business transformation of the U.S. military. It will provide communication updates on deployments, the opportunity for military leaders at all levels to learn new skills, advance their careers and contribute to the success of their organizations.
