Table 3

Simple effect results of spatial filter with each frequency band from the one-way repeated measures ANOVA test of F1 scores.

Source	Type III sum of squares	Corrected degree of freedom	Mean square	F value	value	Partial eta squared
SF at [0.01-1] Hz	1.354	3.463	0.391	76.338	0.000	0.590
Error (SF at [0.01-1] Hz)	0.940	183.548	0.005
SF at [1-2] Hz	0.064	3.551	0.018	2.768	0.034	0.050
Error (SF at [1-2] Hz)	1.232	188.184	0.007
SF at [2-3] Hz	0.030	3.212	0.009	1.397	0.244	0.026
Error (SF at [2-3] Hz)	1.132	170.222	0.007
SF at [3-4] Hz	0.015	2.809	0.005	0.755	0.513	0.014
Error (SF at [3-4] Hz)	1.082	148.867	0.007
SF at [4-5] Hz	0.014	3.318	0.004	0.990	0.404	0.018
Error (SF at [4-5] Hz)	0.728	175.831	0.004

The only significant simple effect of the spatial filter can be found only in the frequency band of [0.01-1] Hz, where the value is less than 0.01.
