Figure 2.

Correlations between different choices of each method are demonstrated for all subjects in both datasets. Each frequency band was considered separately while calculating the correlations. The four bands are highlighted with four different colors. For each method (presented in each row), the remaining methodological choices were kept constant as follows: artifact removal = yes, EEG transformation = raw, filter = Butterworth, time window = 750 ms, and PSD estimation method = Welch’s method. The boxes indicate the quartiles of the samples while the whiskers extend to show the rest of the distribution up to 1.5 inter-quartile range. The dots indicate the outliers.
