I still can't figure out the weighted ratings

So what's the deal with the weighted ratings? How are they calculated? It's not enormously important, I'm just curious about the method and thoroughly confused.

I've got 25 ratings, 22 of them 5 and 3 of them 0 by some shitty users and still am only at 4 avg. I don't know how it works, but it doesn't seem like it represents the views of users

Oh, sorry:

c0sm0nautt said: I don't bother giving out any 0's because I don't see a need for it, but give out 5's when they are due. So why should my 5's be worth less? Seems a little flawed to me.
That's not exactly how it works... the normalization accounts for mean and standard deviation, so your 5's are not heavily adjusted since most people on the BB give out a lot of 5's. The main effect of the normalization on you personally is to make your bad ratings worth less (ie. more effective), because you leave fewer than average.
Quote:
Ratings left by c0sm0nautt would be worth these values after normalization: Rating of 0 = -2.1642 Rating of 1 = -0.7738 Rating of 2 = 0.6166 Rating of 3 = 2.007 Rating of 4 = 3.3973 Rating of 5 = 4.7877
Similarly, if a member gives out a lot of bad ratings the value of their good ratings may be worth more, but the main effect will be to increase the value of the bad ratings they've left. Eg:
Quote:
Ratings left by sucklesworth would be worth these values after normalization: Rating of 0 = 1.7788 Rating of 1 = 2.5129 Rating of 2 = 3.247 Rating of 3 = 3.9811 Rating of 4 = 4.7152 Rating of 5 = 5.4493
The main thing to remember is that the ratings left by an individual are normalized based on what's typical of the BB, so you can't predict how it will affect someone based on their rating history alone. You can play around with http://www.shroomery.org/forums/ratingtest.php if you like. Normalization is frequently used in this type of situation to account for disparities in subjective judges, and I think overall it has made ratings a more fair and accurate way to gauge a user's reputation at a glance.
Quote:
Heh... when a user leaves a rating, the equation to calculate its normalized value is:
adjusted_rating_value = all_ratings_average + (all_ratings_standard_deviation * (rating_value - user_ratings_average) / user_ratings_standard_deviation)
It's based on the principles explained here.
Then a person's grand score is the average of these normalized ratings, rounded to the nearest whole number.
The two users you're asking about actually work great as an example since they only have a few ratings.
Cension, with a score of five, received a single five-shroom rating from PrimalSoup. PrimalSoup has only left a few ratings so they're not being normalized yet. His five is worth a five (for now).
wygram, with a score of four, received two five-shroom ratings, one from you and one from vinsue.
Quote:
Ratings left by RogerRabbit would be worth these values after normalization: Rating of 0 = -6.32 Rating of 1 = -4.1528 Rating of 2 = -1.9855 Rating of 3 = 0.1818 Rating of 4 = 2.3491 Rating of 5 = 4.5163
Quote:
Ratings left by vinsue would be worth these values after normalization: Rating of 0 = -8.6308 Rating of 1 = -6.0087 Rating of 2 = -3.3865 Rating of 3 = -0.7643 Rating of 4 = 1.8578 Rating of 5 = 4.48
So his rating is (4.5163 + 4.48) / 2 = 4.49815, which is rounded to four. Obviously he's right on the edge and it's likely his next five-shroom rating will push him over the top. I hope this makes sense although I can see how this case was particularly confusing.

god forbid whoever pisses me off enough to leave a 0 rating, or even anything ≤ 2 for that matter.
Ratings left by Acidic_Sloth would be worth these values after normalization: Rating of 0 = -10.1027 Rating of 1 = -7.17 Rating of 2 = -4.2373 Rating of 3 = -1.3046 Rating of 4 = 1.628 Rating of 5 = 4.5607

The deal is that the admins of this site decided that the rate you intend/want to give is not always the rate you get to give.

Your link to the ratingtest page brings you to a blank field of white in both Firefox 22 and IE10.

You should really update your Firefox, the FBI was using exploits in older FF builds to track people down that were using Tor. If it can work on the Tor build, it can work on the regular build.
I'm on FF24 and experiencing the same thing, howerver.
