Table 2 shows the results of one-way between-group MANOVAs and MANCOVAs, performed separately for the reference and relative θ power. The results for the MANOVAs (presented in the previous section), show that for the group effect is significant for both the reference θ power (F(5,90) = 3.141; p = .012) and the relative θ power (F(5,90) = 4.527; p = .001), with the size of the effects accounting for 14.9% and 20.1% of the variance respectively.
