Note the sphericity violation across positions means we should NOT report the sphericity assumed statistics for the position effect or it’s interaction

Tests the null hypothesis that the error covariance matrix of the orthonormalized transformed dependent variables is proportional to an identity matrix.a
a. Design: Intercept
Within Subjects Design: Frequency + position + Frequency * position
b. May be used to adjust the degrees of freedom for the averaged tests of significance. Corrected tests are displayed in the Tests of Within-Subjects Effects table.
