Because people do not think of stars as intervals, but as their upper bound reached. In this case, the average would be 2.5 – whereas yes, if you consider stars an interval, then yes, the 2-3 interval is average, but virtually no-one thinks this way.
- crazygringo 3y agoWhen you're giving stars there's no such thing as intervals or bounds. You have 5 discrete options from 1 to 5. Perhaps the confusion here is on whether it's possible to give 0 stars. If you're rating from 0 to 5 then you could consider the midpoint to be 2.5 rather than 3. But generally things like Uber and Amazon have a minimum of 1 star, so the average is not 2.5, but 3.
- shakow 3y agoYes, but stars are not punctual on your screen. What people see are the stars filled up to the third star, whereas the average score would look like the third star being only half-filled.
- crazygringo 3y agoNo it doesn't. The lowest score looks like one star filled, the highest is 5 stars filled, and the midpoint is 3 stars filled. If the third star is only half-filled then that would be produced by a mix of half 2's and half 3's. Not all 3's. All 3's results in three stars filled.
