Would it be correct to say that a 3.5/5 movie rating on a 0.5/5 scale isn’t exactly the same as a 7/10 rating on a 0.5/10 scale, even though it seems like it mathematically? The reason is that half a star on the 5-point scale visually represents less than a full point on the 10-point scale. So, while a great scene might earn you a half-point bump, it wouldn’t necessarily add a full point on the 10-point scale. If rated on a 10-point scale, it’d probably be closer to a 6.5, which converts to 3.25/5 or simply 3/5 on the 0.5/5 scale. This shows that converting ratings to different scales don’t always align perfectly with your intended rating.
Would I be right claiming this?
If there are the same number of values then the scales are identical, as you mentioned. There might be some differencss in how it is perceived on the individual level, but it doesn’t mean they are not the same scale.
For example, a numbered scale to me invites more comparisons to other values because they are numbers. This makes them feel less accurate when I disagree about whether one similarly scored movie is better than the average score. Stars don’t have this same urge for me, but might for someone else.
I kind of like the rotten tomatoes idea of whether something is mostly liked or not, because it doesn’t encourage comparisons.
yes why they are identical scales with same numerical values, i’d argue that each scales visual representation be it smiley faces or numbers would have a different consumer meaning in what would be considered bad, average, good etc… for example a 3,5/5 smiley faces can be seen as above average, but it’s equivalent 7/10 would be considered good if not very good when looking at a number scale, so yes while they both have the same mathematical value, it all boils down to on how WE perceive THEIR value, wouldn’t you agree?
I agree it can be peeceived differently to the viewer, although that doesn’t mean that the person doing tthe review will rate it differently for different visual scales. Someone who has a five star rating system would most likely have the same scoring method and end up with the same proportional rating outcome.
So if a great scene is half a star it would also be .5 of a numbered rating that matches the number of stars.
Yes I agree, but my point is that if a reviewer does not have a proper scoring method and rates everything on feelings and what looks right, that different visual scales would have a psychological effect on his final score between the scoring systems.
