I found a better way, look ! Smilie

cat data.txt | awk -F, '{for (i=4;i<=NF;i+=2)if($i>=5){deg[$2]+=$i;count[$2]++}}END{for(i in deg){print i " has avg "deg[i]/count[i]}}'

Jordan Mary has avg 7
Leven Kate has avg 6
Owen Chris has avg 6.5

I agree, that is of course more straight forward and more importantly, more legible. Mine is obviously more artficial and more "spielerei"....
You can leave out the cat BTW:
Code:
awk -F, '{for (i=4;i<=NF;i+=2) if($i>=5){deg[$2]+=$i;count[$2]++}}
          END{for(i in deg){print i " has avg "deg[i]/count[i]}}' infile
