The quadratic mean ( or root mean square ) of these values is taken, similar to a standard deviation calculation.
2.
The Quadratic mean ( often known as the root mean square ) is useful in engineering, but is not often used in statistics.
3.
Plotting the logarithm of the number of trees per acre against the logarithm of the quadratic mean diameter ( or the dbh of the tree of average basal area ) of maximally stocked stands generally results in a straight-line relationship.
4.
The quadratic mean of the end-to-end distance \ left \ langle r ^ 2 \ right \ rangle can be related to the quadratic mean of the radius of gyration \ left \ langle s ^ 2 \ right \ rangle of a polymer by the relation:
