For example, if Mauchly's Test of Sphericity is significant or the Epsilon value is
low. n The most popular test is Wilks' Lambda. From this we can see that there is
a significant main effect for our repeated measures factor 'time', F(2,9) = 135.93; ...

The relevant assumption of sphericity is violated when the variances of difference
scores among pairs of levels of a repeated-measure IV are unequal. That is, the
variance in difference scores between two adjacent levels (e.g., a, and a2) is ...

There are two aspects of shape: sphericity and form. Sphericity is a quantitative
parameter measuring the departure of a body from equidi- mensionality. Sneed
and Folk (1958. pp. 117- 25) review the various measures of sphericity and ...

Particle shape can be described by parameters such as sphericity and
roundness.'13'14' Sphericity refers to the degree to which particles approach
spherical shape, whereas roundness describes the angularity of particle corners.

Measurement of Blast Fragmentation
1.2 Axis Ratios Studies of fragment shape have been advanced to a
considerable degree in geological applications, where sphericity and roundness
are important measures of sediment abrasion during transportation by rivers or
glacial ice.

Note that compound symmetry is simply one form of sphericity; a vari- ance-
covariance matrix which shows compound symmetry also shows sphericity by
definition. If the sphericity assumption is not met, then the F test for treatments in
RCB ...
