Table 1. Mauchly’s test of sphericity for testing raw data.

Mauchly's test of sphericity was examined to test for equality of variance. Since the Sig. probability (.000) is less than .05, the variances among the three sets of scores are not equal, which means that a statistical correction is necessary due to the lack of homogeneity (equality) of variance.
