I'm making a simple rating system, just like youtube has:
This works great if you have a big userbase, but it's too sensitive with just a few votes.
Say the first vote is down, no green bar will be displayed.
Or when you have two votes, with 1 downvote, results in a 50%
While this is the actual result, it's a bit too fragile. Are there any common methods to overcome this? I'm thinking of starting with stats like 10up/10down, that'll ease the influence of 1 vote, but that makes me start at 50% if no-one voted (now default is 100%).
I'd like a fair method, where one vote doesnt have to much influence? I'm the techy, I can work with a formula.
Edit, Extra info after some answers:
- I'm not expecting much votes in a small timewindow, therefore hiding the bar until X votes are placed doesn't have a preference.
- I'm not going to add 'x votes', I don't want to give away that we have a low amount of votes (for now)
