sphericity
- noun
- /sfɛrˈɪsɪti/
- Specialized
- The scientist measured the sphericity of the particles to determine their suitability for the experiment.
- sphericity test
- sphericity assumption
- violation of sphericity
Examples
-
A Mauchly sphericity test supported assumptions of homogeneity of variance.
Academic text (1997) -
The sphericity assumption was not met, so the Huynh-Feldt correction was applied.
Academic text (2004) -
The Geisser-Greenhouse correction was employed in order to test for violations of the sphericity assumption.
Academic text (1991) -
First, in order to find out whether the scale is suitable for factor analysis, a KMO and Bartlett's test of sphericity was conducted.
Academic text (2010) -
The assumption of sphericity was violated; thus, we used the Greenhouse-Geisser correction to identify significant group differences.
Academic text (2014) -
Bartlett's tests for sphericity confirmed that multivariate analyses were appropriate in each case.
Academic text (2003) -
When Mauchly's test indicated a violation of the assumption of sphericity, degrees of freedom were adjusted using the Greenhouse-Geisser correction.
Academic text (2018) -
Without ever recognizing the sphericity of the earth, they had grasped enough knowledge of celestial mechanics to enable them to predict eclipses.
Academic text (1992) -
Consequently, degrees of freedom were corrected using Huynh-Feldt estimates of sphericity (e = 0.895).
Academic text (2010) -
Mauchly's test indicated that the assumption of sphericity was violated (χ² = 42.982, df = 14, p = .001).

Etymology
Sphericity comes from the old Greek word sphaira, meaning 'ball', and it is the same root as the familiar words sphere and spherical. So sphericity is simply how much something is like a ball or how 'round' it is.
