Sure, lots of hints! [zl.median] gives you the median of a list. CNMAT has a free "everything" package that contains standard deviation as a separate Max file (see: 

 Your biggest challenge probably is getting the columns out of your [coll]. If you give it a "dump" message you can can extract the columns with [unpack 0 0 0 0] and [thresh].
