title: Most appropriate test for identifying if one group has significantly higher variance in its samples, than another?
body: <p>I am conducting analyses on fMRI (neural) data. There are two brain regions of focus, region1 and region2. For each region, there are 5 subjects worth of neural data (5 samples). Each sample is shaped as 72 x 79 x 95 x 79 x 4, or collapsible to 79 x 95 x 79 x 288.</p>
  <p><strong>I want to establish whether there is higher variance in the data between subjects in region1, than there is variance between subjects in region2</strong>.</p>
  <p>What statistical test would you recommend to assess this?</p>
  <p>Many thanks in advance!</p>
