Hi Meagan,
if you want to average over a square region, use the Fast Filters plugin
with radius=4.
"Fast Filters" is either in the Plugins>Filters menu or you can download
it from
http://imagejdocu.tudor.lu/doku.php?id=plugin:filter:fast_filters:startIf you want to average over a circular region, use the built-in
Process>Filters>Mean command with a radius of 4 or 4.5 (see
Process>Filters>Show Circular Masks for the regions used)
