As currently used, the Alzheimer's Disease Assessment Scale- Cognitive subscale ( ADAS-Cog) has low sensitivity for measuring Alzheimer's disease progression in clinical trials. Thus, if an experiment is repeated, under the same conditions, same pattern of systematic errors reoccur. If any error deviates from the mean by more than the maximum permissible error, it is considered as a gross error and the measurement is rejected.

Gross errors, also known as blunders or mistakes, are results from. Where v1, v2, v3 and v1n are defined as residuals calculated as the difference between a measurement and the mean over a set of measurements. They are deterministic and can be remedied by applying proper corrections. The sing of this correction is always plus (T) as the effect of pull is to increase the length of the tape and consequently to decrease the measured length of the base.
