Announcement The Coop Page / Article Rating & Review Project!

[Cyprus]

I always use weighted average when rating things

Good
I was explaining for the people who didn't get how it worked
Did you learn it in school?

   // same as the xf resource manager to maintain a standard.
    public static $voteThreshold = 10;
    public static $averageVote = 3;

    public function getWeightedRating($count, $sum)
    {
        return (self::$voteThreshold * self::$averageVote + $sum) / (self::$voteThreshold + $count);
    }

As @Nifty-Chicken kindly included, this code is what the site is using.
It is taking our vote threshold, multiplying it by the average vote and adding the sum (total number of stars). It is then dividing that number by the vote threshold + the total number of reviews.
vote threshold = 10
average vote = 3

10 x 3 + total number of stars/ 10 + number of reviews
Take an article with 5 reviews and a total number of 18 stars
10 x 3 + 18/ 10 + 5 = Rating

Yea, it sorta works the way ice hockey goalie's goals against average stats are kept. This ensures that a goaltender who gets no goals against in one game played doesn't hold a higher standing than a goaltender who played 54 games with a 2.10 goals against average. I know there is barely anything in common with goalie stats and chicken coop ratings but it is the same idea

I sure did learn it in school As a kid I was oddly fascinated by the art of keeping statistics

I'm just at the fact that the Canadian remembers Bayesian average statistics because it related to Hockey!!!
Boy, if I didn't already know you live in Canadia

Awesome! I haven't taken statistics lol.
I just taught myself how to use that statistic in about 2 minutes before I replied.

That makes more sense to me. Thanks. Am not math head, at all.
...and it makes more sense to apply it to sports stats, than coop pages in the net.

Oh boy now I'm determined to get them all!! 5 in and still ready to go!!!

Yall are going to get tired of seeing my post of them ​

 

[Nifty-Chicken]

I lost my spot and am now randomly choosing.

Sorry, but I'll be updating the list constantly, so picking at somewhat random is probably the best way to go

BTW, I should have done this earlier, but check out this data on the number of reviews for coops under 5 ratings:

... and if I don't limit the query to only those below 5, here's what we get:

YAY FOR DATA!!

That's how our entire house hold is . We identify American cities by the team that plays there . Like I'll see a picture of the Gateway Arch in St. Louis and say "hey, there's the place where the St. Louis Blues play in

That makes more sense to me. Thanks. Am not math head, at all.

Ah, it's a handy thing and makes more sense to use than normal average
