I like to invite your thoughts on the assignment of stars to average
A user has five choices for her vote: 1 to 5,
corresponding to 1 star to 5 stars. Each star carries 20 points, so a
vote is between 20 and 100. The average is calculated as the
arithmetic mean of all the votes: the sum divided by the number of
The script implements the following allocation of stars to the
$rating >= 90 5 stars
$rating >= 85 4.5 stars
$rating >= 80 4 stars
$rating >= 70 3.5 stars
$rating >= 60 3 stars
$rating >= 50 2.5 stars
$rating >= 40 2 stars
$rating >= 30 1.5 stars
$rating >= 20 1 stars
$rating >= 10 0.5 stars
$rating = 0 0 stars
Is this acceptable or realistic?
Note you get 5 stars for an average over 90, not 100
(which would be very hard to achieve).
Then only 5 points lower is 4.5 stars, and again 5 points lower 4
stars. After that it is an even descend.
And you never get 0.5 stars, since the lowest vote is 1 star.
Any thoughts on this please?
