Jesus. If you want proof, look at literally any rating system, like on Amazon, Hulu, or Goodreads. The average rating on goodreads is 3.7 out of 5, aka 7.4 out of 10. They’re not all exactly 7, no. But it sure as hell isn’t 5 out of 10. 5 is the middle rating (2.5 is in this case), not the average.

The average high school GPA is 3.0 out of 4.0 — aka 75% or 7.5 out of 10.

It totally varies depending on the data set. It can be 5 sometimes! But that’s coincidental. In a ton of cases, it’s 7-ish.
