@parent2noles no one likes data more than me. 
However, the middle 50% for GPA is a far more useful metric than the average GPA.
Even then, it’s never an apples to apples comparison, as most schools use a weighted GPA and have different criteria in deciding which classes should be used to calculate GPA. We could compare UF to FSU, or compare UC-Berkeley to UCLA but we really couldn’t compare UF or FSU to any University of California school.
Example: FSU GPA=4.02, while UCLA GPA = 3.87 (based on the CDS). The difference isn’t because FSU is more selective (UCLA is FAR more selective), it’s because each school calculates GPA differently.
Why does UF not include it? Who knows. It’s not something it has a reason to hide. Looking at past CDS info, UF has been putting the middle 50% range into that field as far back as 1997-1998 (the oldest CDS info on UF’s website).
