Sphericity, or " deviation from spherical form ", refers to how much the ball deviates from a true spherical form ( out of roundness ).

In Brockport, New York, in 1887, M . C . Flanders argued the case of a flat Earth for three nights against two scientific gentlemen defending sphericity.
43.
"' Monodisperse glass microspheres "'have high sphericity and a very tight particle size distribution, often with CV 95 % of particles in size range.
44.
If the variances of differences between all possible pairs of groups are equal and sphericity is exactly met, then epsilon will be exactly 1, indicating no departure from sphericity.
45.
If the variances of differences between all possible pairs of groups are equal and sphericity is exactly met, then epsilon will be exactly 1, indicating no departure from sphericity.
46.
When epsilon is > . 75, the Greenhouse-Geisser correction is believed to be too conservative, and would result in incorrectly rejecting the null hypothesis that sphericity holds.
47.
This analogy with a curved egg led some modern historians, notably Joseph Needham, to conjecture that Chinese astronomers were, after all, aware of the Earth's sphericity.
48.
The grains in the member have a high degree of sphericity, are very well sorted and typically have a small size range ( 0.5 mm to 2 mm ).
49.
The flat-Earth myth, like other myths, took on artistic form in the many works of art displaying Columbus defending the sphericity of the Earth before the Council of Salamanca.
50.
The test statistic for these estimates is denoted by epsilon ( ? ) and can be found on Mauchly s test output in SPSS . Epsilon provides a measure of departure from sphericity.
