*Used trim mean 5% (trimmed mean of the values in X is the mean of X, excluding the highest and lowest K data values, where K = N*(PERCENT(=5)/100)/2 and where N is the number of values in X. Values reported for each subject is the average value of the metric over all 8 channels and entire recording.
