Why is rating messed up? I rated an instructable at 1 star, and it then gave it 4 stars. (There were no other ratings)? Answered

The only solid ground I have to work on was (again a rather poor from memory quote): "the more active a user is the more heavily their vote is weighed"

Because the system is weighted towards 5 and it would take a fair number of people to bring an ible down. Basically don't vote if it sucks.

It also weights in how much the user uses the site; comments, ibles, ratings, etc -- if all you ever do is rate things negatively, your votes will be worth less. The author has 1 ible and a handful of comments - so that algorithm is just going to throw it away.

Thanks! (I don't go around giving negative ratings, though.)

well, be more active in the community, and see my reply to sean above - its my interpretation of how a low vote averages to a high result for the first several votes.

I read from someone who works the site:
(my interpretation) its based on an algorithm that incorporates how active a community member you are, the average site rating of all ibles (to get a baseline of what average really is), how many engagements the voter has, etc.

Basically what it sums up to in MY estimation is that a good 5-10 votes pad the actual the votes tallied as 'average site ible rating', and those averaged pad votes are bumped out as more people vote:
say average is 4.0
someone votes one
ible rating is 4+4+4+4+4+4+4+4+4+1 averaged is 3.7
another one
4+4+4+4+4+4+4+4+1+1 averaged is 3.4
someone votes 5
4+4+4+4+4+4+4+1+1+5 averaged is 3.5

and the weight your actual vote has (calculated before its added to the above formula) would be a factor of how many times you have voted, number of comments made, number of ibles published, etc. I haven't the foggiest the math behind this.

Maybe your credibility is taken into account when you rate an instructable.
The higher your credibility the higher the STARS.
