Sphericity: the variances of the differences between all combinations of the related conditions/ time points are equal (similar to the assumption of equal variances in ANOVA). Mauchly’s test of Sphericity is automatically given in the output. If p > 0.05, Sphericity can be assumed. Use the p-value from the Greenhouse-Geisser correction from

Violations of Sphericity and Greenhouse-Geisser Corrections ANOVAs are not robust to violations of sphericity, but can be easily corrected. For each within-subjects factor with more than two levels, check if Mauchly’s test is significant. If so, report chi-squared (χ2), degrees of freedom, p and epsilon (ε) as below and report the

Sphericity is independent of roundedness, and measures how close a grain comes to being spherical or elongate. Figure 3. Sorting is a measure of how even the particle size distribution. Sample A is poorly sorted while sample B is sorted.
