In terms of scientific investigation, the definition of reliability is the presence of a stable and constant outcome after repeated measurement (Jackson, 2014). Regarded frequently in early research, Absolute constant error (ACE) -> in a group setting, how far group is from target on average, New skills will have more error, as they familiarize the errors get less, Constant error: stabilizes after a few trials (closer to the target) Imagine a test is administered to measure athleticism in various sports teams; however, one of the tested teams had food poisoning the same day.
