<div>Dear fieldtrippers, </div>
<div> </div>
<div>I want to compare the global field power in two different conditions over several participants. I have computed time-locked averages for both conditions for each participant separately. </div>
<div> </div>
<div>My first question now is, should I first compute a grand average over all participants and use
<pre class="code matlab" style="padding: 0.5em; margin-top: 0px; margin-bottom: 1em; margin-left: -10px; font-size: 12px; border: 1px dashed rgb(204, 204, 204); overflow: hidden; font-family: Consolas, 'Andale Mono', Menlo, Monaco, monospace; width: 640px; text-align: justify; background-color: rgb(247, 249, 250);">ft_globalmeanfield</pre>
</div>
<div>on this or should I first compute global mean field for every participant and then average over them? Additionally, which functions should I use for those kinds of averaging?</div>
<div> </div>
<div>The second question would be, has anyone any recommendations for a statistical test I could use to see whether the conditions differ in global mean field power?</div>
<div> </div>
<div>Cheers, </div>
