How do I take good photography, video or audio in the field? 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) To determine stability, a measure or test is repeated on the same subjects at a future date.

Scribbr. Internal Consistency. Anne failed to achieve the goal of the game by hitting the center of the board, therefore it was not valid. Reliability can be estimated by comparing different versions of the same measurement. Reliability shows how trustworthy is the score of the test. This includes the chosen sample set and size, sample preparation, external conditions, and measuring techniques. : an American History (Eric Foner), Forecasting, Time Series, and Regression (Richard T.
