New Updates: https://www.beeradvocate.com/community/threads/new-ba-score-histograms-more-updates-part-two.538899/ ---------- Greetings! The following updates will be rolling out over the next few hours, so we wanted to give everyone a heads-up just in case you come across an update in the works. ---------- The TL;DR The BA Score is now the percentage of raters who gave the beer a 3.75 or higher. We're now telling a more complete story behind a beer's ratings, and beers are being scored on their own merits vs. being scored against all other beers. The basics have been applied to breweries and other places, too. Keep on reading to learn more. ---------- Goodbye, BeerAdvocate Overall Score (BOS). The BOS was a proprietary weighted point system that represented the final overall score for a beer. Based on a weighted rating, its purpose was to help make some sense out of the beer's average across all ratings and provide consumers with a quick reference when comparing one beer to another. Why we're ditching it: Its 30-100 point scale was a seemingly arbitrary, dated standard that was borrowed from the wine and spirits world. In my opinion, this point scale is designed for shelf talkers and tends to favor higher scores. Many confused it with being a percentage. It failed to clearly or quickly tell consumers what the rating community really thinks. Beers were being scored against all qualifying beers, instead of being scored on their own merits. We also assigned text (world-class, outstanding, very good, good, okay, poor, and awful) to the BOS ranges to further help explain the overall consensus. We're saying goodbye to this, too. Instead, we're going to tell a more complete story about the beer's ratings and empower consumers to make a better, more informed, decision for themselves. Hello, BA Score. It's Just Math. The BA Score for beers is now loosely inspired by Rotten Tomatoes' Audience Score and is represented as the percentage (rounded to the tenth for depth) of raters who gave the beer a 3.75 or higher. (number of ratings >= 3.75 / the number of ratings) * 100 After analyzing the data and reviews we determined that a 3.75 or higher was a clear indication that the beer was, without a doubt, liked. It also matches the bar that's been raised by consumer and industry expectations in recent years. We also anticipate that each user will eventually create their own percentage threshold of acceptance. For example: I might consider a beer with a BA Score of 48.7% as worth a try as nearly half the people who rated the beer really liked it, whereas Jason might not consider trying any beers without more of a consensus (say 60% or higher), and you might be totally fine exploring beers that are under 25%. But we're going to allow you to decide what's "world-class, outstanding, very good, good, okay, poor, and awful." A beer must still receive 10 or more ratings before a BA Score is applied. Liked The number of users for the given item who rated it a 3.75 or higher. Liked This Beer: across all ratings/reviews for the beer Liked Their Beers: across all ratings/reviews for all active beers Liked This Place: across all ratings/reviews for the place The number of liked ratings appears under Beer or Place Stats accordingly for reference. Ranking The BOS is gone, but we didn't ditch the underlying weighted rating (WR) system. All qualifying beers (active with 10 or more ratings) are now given a ranking based on their WR. This directly correlates to our main top 250 beers, and allows readers to quickly determine if a beer lands within the top 250 (a highly requested feature) or where it lands among all qualifying beers. Additionally, we plan on taking snapshots of a beer's ranking to add even more depth to a beer's rating history here on BA. Rankings are updated on a daily basis. Beer Average Previously, the beer average was weighted based on each user's rating history. It's back to a straight average now, which considers the ratings of all users equally. This will no doubt shake-up the beer rankings. Beer Shelf Talkers Have been updated to support the above changes, but are rounded to a whole number for readability and to offset minor shifts to the tenth, which will give them more longevity. Top Beers Threshold for Consideration Previously this was the average number of ratings across the data set, which was used throughout the WR calculation. We still use this number in the calculation, but the threshold to be listed is now 10 or more ratings to support the new ranking and to help flush out lists that had small data sets. Bros Score Based on reviews by Jason and I, our Bros Score has been retired from focus on lists and beer pages. It's still displayed under a beer's stats as a historical nod to the site's origins, but we felt that it's important to put all the main focus on the rating community's opinion (BA Score). And when displayed, it's just a rating or average now. That's it for now. Browse around and feel free to let us know what you think. Cheers!
