<p class="MsoNormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I have the minimum, maximum and mean alpha power for each MEG sensor (found using MEGProcessor developed by Jing Xiang, MD, PhD) for
16 subjects, 8 of whom have a psychiatric condition and 8 are healthy comparison subjects.

<p class="MsoNormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">We find statistical significance when comparing the set all of the MLF or MRO sensors, for instance, between the groups (healthy and
pathological), however, I am wondering if this is false statistical power as all of the sensors likely represent once source generator and not truly, multiple, separate, non-independent recordings. Would it be best to summarize each subject’s data with one
number to represent the maximum alpha power for the group of MLF sensors and then compare the two groups of subjects?<o:p></o:p></span></p>
