Oh, so many posts to respond to! (read: my post is going to be huge.)
First, I'm ignoring all posts about ratings being bad or not mattering. Ratings have a unique, useful purpose, and if you really want to contest that, just hold on a few days as I'm thinking I might create a thread to discuss the semantics of ratings. But my point is to leave out such comments as they are off-topic.
Second, those who want ratings to be out of 10, you are misdirected, and please give your argument a little thought before you present it. The ninja display of ratings is an integral part of NUMA. Having 10 ninjas (ex: 8 full and 2 empty for an 8/10 rating) would be annoying. It would be better to just use 5 ninjas, using full ninjas and half-full ninjas to represent all the numbers. But wait, that's the .5 system! As for having 0 - 10 in the drop down box, 0 - 5 is just those numbers halved (if .5's were included), so it shouldn't be a problem.
And now, for the topic at hand. There are 2 different parts to ratings. There's:
1) What values users are allowed to rate, and
2) What values are allowed to show in the average rating.
For example, at
Newgrounds, they use a 0 - 5 system with (1) being whole numbers only and (2) being taken out to 2 decimal places. In my first post, I was saying that whole numbers are fine for (2), but .5's should be allowed for (1), and their removal from (1) was short-sighted. Also, I would like to amend my position on (2) to embracing exclusion of .5's.
Explanations:
For (1), I think users should be able to rate whatever the hell they want. Typically there are other considerations at hand, such as the UI (in NUMA's case, there's a drop-down box that displays all possible values), display of individual votes (like at Newgrounds), etc. Typically this results in a good compromise of the integrals 0 - 10 or 0 - 5. Per my argument above, 5 is extremely likely to remain the upper limit at NUMA. However, if a lot of users are complaining about the inability to use the .5's (and they are), then .5's should be there. Those who want to use them will use them, and those who don't, won't. And if you disagree that a lot of users are complaining, just browse a few random maps. Chances are you'll see a "x.5 rounded up/down" comment. Also, allowing .5's for voting shouldn't be a problem because of the next section.
(2) should use whole numbers only. I had a long discussion with epigone about this on the old forums, and basically my final argument was "4 represents a huge range now, from 3.5 to 4.5", which epigone countered with (something to the effect of) "It doesn't matter if you're looking at maps with 3.5, 4, or 4.5. The point is you're looking at good maps." If you deconstruct that statement, you'll see that he won. There's two reasons for this:
- NUMA is imperfect
- Community consensus != your consensus
Why is NUMA imperfect? Because ratings fluctuate depending on how many people rated, who those people were, and even sometimes what state those people were in at the time. "I agree, but so what?" said I, on the old forums. "Once you get about 10 - 15 votes, your chance error goes way down." If you think about it though, that's not really true. Even at 10 votes it still matters quite a bit who those 10 were. In any case, NUMA is a smallish internet community, and most maps don't even get 5 rates. Even if you exclude noob maps, the average # of rates would certainly be no more than 7 or 8. 7 or 8! Suffice it to say, that's hardly a community consensus.
Which brings me right to the second point, which is that even if NUMA provided a perfect community consensus of all maps, that would not necessarily make the ratings any more useful for users because personal tastes vary considerably.
Thus, as George said:
George wrote:The ratings system doesn't truly reflect the quality of a map, and only exists as a rough measure.
And therefore a more general system is better.
So that's my case for .5's. What do you all think of it?
Some final notes:
For those okay with rating in whole numbers but not liking the absence of an "average" option, please keep in mind that rating out of 5 is an incredibly common system given our base of 10, and furthermore that you don't have to go by what the drop-down menu tells you the specific ratings mean. I have always
despised comparing something against "average" for grading it (because what the hell is "average"?) But in any case, I'm saying you should take the text of "above average" on 3/5 and substitute something that suits your personal philosophy better, be it anything from "neutral" to "pretty decent".
