Standard deviation of errors

The standard deviation of error of prediction (SD) gives an insight into the accuracy of the prediction. If one considers the errors being normally distributed, more than 68% of estimations are performed with an error below SD. 

This comprehensive study also tested the relative importance of the various terms in Eq. (18), and its relative performance when compared with modified Karplus equations of the Pachler, Haasnoot, and Colucci el al. types. Based on standard deviations of errors, the ranking of the four most important terms was found to be cos 2ip, cos

important term is the combined electronegativity/electronegativity orientation term, and the fourth most significant one is the bond angle term, the first- and third-ranked terms... 

Several measures used to help characterize within-run variability in performance include variance of error [Neilson and Neilson, 1980], standard deviation of error [Poulton, 1974], and inconsistency [Jones and Donaldson, 1986]. 

Accuracy of the primary aimed movement can also be characterized in terms of a constant error and a variable error (standard deviation of error), which are considered to be indices of accuracy of central motor programming and motor execution respectively [Guiard et al., 1983].
