Measures of Dispersion - NCERT
ncert.nic.invariation, there are certain measures namely: (i) Range (ii) Quartile Deviation (iii) Mean Deviation (iv) Standard Deviation Apart from these measures which give a numerical value, there is a graphic method for estimating dispersion. Range and quartile deviation measure the dispersion by calculating the spread within which the values lie.

RAMAN SPECTROSCOPY OF GRAPHENE AND RELATED …
www.physics.purdue.eduGraphene is a 2-dimensional (2-D) hexagonal lattice of carbon atoms [Fig. 1(a)]. Its 2-D nature leads to a linear dispersion relation at the K points of the Brilluion zone [Fig. 1(b)], also known as a “Dirac” cone, and this linear dispersion necessarily implies that charge carriers in the graphene have no rest mass, leading
