This stands as a nice example of a positive voting system as described in an earlier article but it seems to be missing something - balance perhaps.
This story also illustrates a range
voting ballot, in this case
having a range consists of the five ratings listed above. To
tally the votes from all the guests over time, the ratings are
assigned numerical values, such as the ones shown, that are added or
perhaps averaged, depending on how the results are to be used.
Like IRV, range voting allows the voter to register different degrees of approval or, in a slight variation, disapproval of candidates.
In another earlier article of this series I introduced a system of voting that I called Balanced Approval Voting and a reader correctly observed that BAV amounted to range voting with three scores in its range. Using BAV, a voter designates each candidate as one of:
Disapprove
Neither approve or disapprove
Approve
To tally the votes, we could use the
indicated numeric values, 1, 2 and 3 or we could use the values -1, 0
and 1 as suggested in that earlier article. Whichever number
assignments are used, the winner will remain the same so long as they
are kept in that order and spaced evenly.
Well, actually that is not quite the case. To be
certain of that claim we must specify that every voter specifies a rating for
every single candidate.
