You've caught this content before I had a chance to format it.

Get the Min, Max, Median, and Average 

of a set of numbers...

I really only needed the min and max. I Googled, and found there wasn't something in the distro that could do this right off the bat.

To same myself, and possibly you, time in your moment of need, here are the best solutions I found. If you find something more elegant, please email me at my callsign via ARRL dot net.

USING AWK

#!/bin/sh
sort -n | awk '
  BEGIN {
    c = 0;
    sum = 0;
  }
  $1 ~ /^[0-9]*(\.[0-9]*)?$/ {
    a[c++] = $1;
    sum += $1;
  }
  END {
    ave = sum / c;
    if( (c % 2) == 1 ) {
      median = a[ int(c/2) ];
    } else {
      median = ( a[c/2] + a[c/2-1] ) / 2;
    }
    OFS="\t";
    print sum, c, ave, median, a[0], a[c-1];
  }




The above I consider a quick-and-dirty solution. There is an impressively wide array of solutions here:
