Sphericity

Sphericity basically describes how strong or whether an object is spherical .

• Sphericity (geology) : a parameter of how well a body approximates the shape of a sphere.
• Sphericity (statistics) : In statistics, an n -variate population is called spherical if all variances match and the correlations disappear, which can be checked for sphericity with the Bartlett test .
• Sphericity (graph theory) : the minimum dimension n , so that a graph can be represented as an intersection graph of a family of congruent spheres in . ${\displaystyle \mathbb {R} ^{n}}$
• Sphericity (algebra) : An algebraic G variety X (to a group G ) is called spherical if a Borelian subgroup operates from G on X and has a dense orbit.
• Sphericity (particle physics) : a parameter in accelerator experiments, how well the geometric shape of collision events corresponds to the shape of a sphere.
