Sentence examples for variance items from inspiring English sources
In the SNS-FEM formulation, a stable item which contains the gradient variance items is constructed without any uncertain parameter to strengthen the system stiffness.
In the present formulation, the system stiffness matrix is computed using the smoothed acoustic pressure gradients together with the gradient variance items over the smoothing domains associated with nodes of element mesh.
Moreover, if R is the covariance matrix of a three dimensional random noise vector, R will be mapped into a real number equaling to the sum of the three variance items of R, while the covariance items are canceled out by (19).

Equality of item-scale correlations: Items in each scale should contain approximately the same proportion of information about the concept being measured.
