Sorry if this is in the wrong place.

How would I determine which items would be more likely to sell? To rank them.

Item1: 4/5 stars, 729 ratings
Item2: 3/5 stars, 861 ratings
Item3: 5/5 stars, 471 ratings
etc…

That would be your decision. What methods of ranking have you been taught?

Please show us what you have tried and exactly where you are stuck.

Please follow the rules of posting in this forum, as enunciated at:


Please share your work/thoughts about this problem
 
My decision on which items would be more likely to sell would be to rank them somehow using their rating. I have not been taught any methods of ranking.

I haven't tried anything yet, since I don't know where to start, hence my asking help from an 'expert.'
 
I didn't provide any more information b/c I wanted an answer based on the info provided.

I guess I would equate the number of ratings with the number of sales, and then rank them by that and then stars.

What is the context of your question? Is this for real-life decision making, or for a class, or what? If it's related to a class, what is being taught?

I would think that it would take experts in marketing, or psychology, or something like that, to translate ratings to sales.

But if this is for a very basic class, perhaps just studying fractions or probability, then they would probably want you just to list them in descending order of the value of the fractions. (The number of people making ratings is probably not very relevant, unless some were very small.)
 
It's not for a class, it's me wanting to know more about math and having a situation where I have some books to sell. (there's another post awaiting approval with more info)
 
If the 3/5 rating took 17 years to get 861 while the other two items got their ratings fairly quickly (compared to 7 years), then that will surely suggest that item #2 is not going to be a big seller.

You say that the helpers here are 'experts' but we are not mind readers. There is much information left out.

Now, if we assume that these ratings came during the same time period AND the items have been around for decades, then that is another story.

But what if the items are all new, then maybe people seeing the review will only buy the item with 5/5 score. Then again, if the 5/5 item costs 15 times the other items, then people may not want to buy this 5/5 items. How would we know which is the correct case?

Are these three items even related to one another? Are any of them outdated (like fax machines or cd players)?

If the items are not related (like a car, a yo-yo and a beach chair), then these ratings are meaningless.

This is not really a question about math. It is more a question about human psychology. Just because numbers are involved does not make something a math question. Math is indeed about numbers. but it is about the relationships between numbers and other things, not human reactions to numbers.

As I said, I'm not sure that mathematical expertise is really what you need; but in order to help at all, I'd want a lot more detail.

You say that you are going to sell some books; are you just selling one copy of each book, or thousands? Where did these ratings come from? Book sellers? Bookstore customers? Reviews of library books? Some ratings reflect a judgement of the site's customer service more than the item sold. Are you thinking about how ratings reflect the existing amount of sales, or how they will influence future sales?

Are you assuming that most people who buy an item rate it, or are you taking into account that certain people will be more motivated to rate an item for personal reasons? I would never assume the number of ratings implies popularity (either before or after the rating was given!).

If you said more about the nature of the data, we could at least make guesses as non-experts in marketing. Without it, all we can do is make guesses about the nature of the question.
 
From our self help series of books, "How to stop rating things", 5/5 stars, 1255 ratings ;)
