Hi,

I'm working on the results page now and I am wondering if I should count "not voted" as 0, or should I try to skip those? 
Another example to clearify:

- 3 sets
- 4 voters
- To make it simpler; there are only 1 statement per set.

Set 1:
   Voters: 3 of the 4
   Vote sum: 3 + 2 + 4 = 9
   Average one: 9 divided on 3 voters = 9 / 3 = 3
   Average two: 9 divided on 4 voters = 9 / 4 = 2,3

Set 2:
   Voters: 1 of the 4
   Vote sum: 3 = 3
   Average one: 3 divided on 1 voters = 3 / 1 = 3
   Average two: 3 divided on 4 voters = 3 / 4 = 0,8

Set 3:
   Voters: 0 of the 4
   Vote sum: 0
   Average one: 0 divided on 0 voters = 0 / 0 = --
   Average two: 0 divided on 4 voters = 0 / 4 = 0


Should we go for average one, or average two? As you can see, the results differ a lot. If we go for average one, you can see
that Set 1 and Set 2 have the same average and are ranked the same although only 1 did vote on Set 2 opposed to 3 on Set 1.

This boils down to: Should those who don't vote on a set at all count as vote 0 in th overall average?
