My website has lists of images and a simple rating system that uses thumbs up and thumbs down votes. Now I want to be able to sort the list page by "Highest Rated" (as well as "Lowest Rated"). However, I don't know the "expected" way to do this as there are multiple ways:

1. Sort by the number of upvotes

This satisfies the "highest rated" aspect, an image will 1,000 upvotes is higher rated than an image with 5 upvotes. However, what if that same image has 10,000 downvotes. Is it really higher rated than an image with 5 upvotes 0 downvotes?

2. Sort by ratio of upvotes

So an image with 1,000 and 10,000 downvotes will only have a upvote ratio of 1:10 or 0.1, while an image with 5 upvotes and 3 downvotes will have a ratio of 1.6, thus it will take into account both ratings to give a more accurate depiction of how it was rated. However, that mean an image with 1 upvote and 0 downvotes will be higher rated than one with 1,000 up and 1,001 down, which at face value might look confusing.

Which way of sorting ratings will make the most sense to the users?

  • It sounds like you might have to create your own system of what is "the highest rated." In my opinion, I think that could be done by accounting for the number of upvotes vs downvotes vs total. So for instance the 1,000 - 10,000 of 11,000 which really gives it a low rating (only 1K is positive, which means it is 9K in the red) VS 5 - 3 of 8 should ideally give it a good rating because it IS in the positive. But it should rank lower than something that got, say 1,000 - 200 of 1200. I guess what I'm trying to say is that 9K negative is still negative, which is a pretty low rating.

  • @Majo0od Hmm, that is a good point. Perhaps I could do something like take the ratio I mentioned in #2 and then use the total votes # as some sort of multiplier. So that 9K negative carries more weight than 3 negative. Although that might be so complicated users will not understand it.

  • I don't think so. You're not showing the math, you're just showing the list.

  • Showing the list with your suggestion will be enough and users will just click on what is recommended.

  • @Majo0od I actually found a duplicate now with an answer saying to do pretty much that so I think thats the way! Thanks
