Well, I wrote a program to download all the ratings from MAL's "Top Anime" rankings. The results are fairly interesting:

mean: 6.943603
std: 0.725463
min: 2.64 (I didn't include shows with no ratings, and this is the only one below 4.5)
25%: 6.46
50%: 6.94
75%: 7.44
max: 9.21

As you can see, Japanese cartoons truly are ichiban - out of more than 6,200 series/movies/OVA's, the average rating is almost 7/10, and a mere 26 were rated under 5/10. This means that only 0.415% of all Japanese cartoons are considered below average! If you would like to see a histogram of my data, as well as an adjusted histogram of what the ratings should look like if not for the absurd rating inflation, here is the path to my imgur album: /a/ebwRv

Interesting. Although, I'd say 50% of entries in the MAL database have very few viewers. Some only have a handful viewed by some of the elite users such as spacecowboy *****_Baer, Ts*taee, and DateYutaka (it's crazy how much anime they've seen).

On MALgraph it says that the average MAL user has a mean score of 7.57.

Damn censors.

I've only recently heard of MAL, but my guess is that most users only review a handful of shows that they liked, while power-users probably tend to give lower average ratings.

I'll go back through the site and filter out shows with >5000 members like IMDB to gauge popularity, though that will probably bring the average rating up a bit. It also shouldn't be too hard for me to measure average rating by category. The only extra work would be finding where that information is in the HTML; getting the information is actually rather fast because I'm downloading 15 pages concurrently.

That's what I was trying to imply. The average user has only about 100-200 completions in their list and don't take advantage of the full 10 point scale. The mean score is so high because most people only rate with 6-10.

While generally people who've seen a lot have more diversified ratings.

Huh. I didn't realize those rankings are weighted:

Weighted Rank (WR) = (v / (v + m)) * S + (m / (v + m)) * C

S = Average score for the Anime (mean).
v = Number of votes for the Anime = (Number of people scoring the Anime).
m = Minimum votes/scores required to get a calculated score (currently 50 scores required).
C = The mean score across the entire Anime DB.

Considering that I've calculated that the mean score C is 6.94, it's apparent that the weighting system is almost totally useless. If the anime has few votes, the first weight will be small and the second weight large. If the anime has greater than 1000 votes, the first weight will be large and the second will be large. This still gives a slight advantage to more popular anime, but the difference will be less than 1 point.

In terms of quality: theoretically an anime with a mean rating of 0 and 50 votes could still pull a 3.5 overall. That's probably unlikely though, as the worst anime apparently earned an average rating of 2.6 on 6227 votes.

Heh, no wonder the ratings are so tightly clustered...

I dunno why you guys are so fussed about MAL scores personally. I thought we all established ages ago that the quality of a series is generally not able to be represented purely by numbers, whether that be in scores or in fanbase. Hence the reason I dont bother maintaining a list.

As for Higurashi, I'm leaning toward a multi-part, singular arc OVA, though thats based purely on the name and the trailers, not ny hard evidence since details arent exactly flowing in.

I agree with i Revive, I never give ratings below a 4/10, because to me if it's bad it's bad. I wouldn't know the difference between 4/10 and 3/10, but I do know it's both not worth watching. :P On my personal scale a 6/10 is average, 5/10 is below average and 4/10 is bad.

Looking at MALgraph I gave 536 ratings with a mean score of 7.40, which is ''0.17 points lower than global average'' according to MALgraph.

@Jesse: Yes, but individual ratings are still interesting. I like looking at someone's list and see what shows they like the most, which would be the ones they gave 10/10 or 9/10. I also use my own ratings in order to decide which show to buy next.

Did you just become a mod within the past 4 days?

@Jesse, I agree. I don't usually pay attention to ratings because I've found plenty of great anime rated lowly (by MAL standards). I have a list just so I can keep track of every anime I've watched, not necessarily to rate.

I have 937 rated with a mean of 5.77, which is "1.80 points lower than global average." 6/10 is also the category with most of my ratings, which is what I consider my average show, since I tend to enjoy anime as a whole. I would still recommend 6/10s.

5/10 is just something I thought was meh. I can't accept it as good nor bad, so it just gets stuck in the middle.

A 4/10 might be something I enjoyed a little but still recognize it as being inherently bad. 3/10 ratings and lower are just grouped as "which ones did I hate more?"
