De jugón a jugón / Re: ASCENSIONES IMPARABLES EN LA BGG (2010)
« en: 24 de Enero de 2010, 21:37:57 »
A ver, lo del rank no tiene ningún secreto. Cito la sección de FAQ's de la BGG:
What is the Difference Between BGG Rating and User Rating?
"If you look at a list of games within BGG you may see a BGG Rating number between 1 and 10. If you then click on that game and go to the game's main page you will see a User Rating and an Average Rating. Most of the time, the BGG Rating number will be different from the User and Average Ratings. Why is this?
The User Rating of a game is the Average Rating rounded down to 1 decimal point. The Average Rating for a game is the average of all ratings from registered BGG users that the game has received, calculated by adding up all individual ratings and dividing by the number of ratings.
The BGG Rating is based on the Average Rating, but the number is altered. BoardGameGeek's ranking charts are ordered using the BGG Rating. To prevent games with relatively few votes climbing to the top of the BGG Ranks, artificial "dummy" votes are added to the User Ratings. These votes are currently thought to be 100 votes equal to the mid range of the voting scale: 5.5. The effect of adding these dummy votes is to pull BGG Ratings toward the mid range. Games with a large number of votes see their BGG Rating alter very little from their Average Rating, but games with relatively few user ratings will see their BGG Rating move considerably toward 5.5. This is known as "Bayesian averaging" and a quick search of both BGG and/or the Web will reveal much discussion on the topic.
In effect, usually the games with many votes will Rank higher than those games with the same Average Rating but fewer votes. "
