## How to Analyze Grade Distribution
Grade distribution shows how student performance is spread across letter grades.
### Formula
**Percentage = Count at Grade / Total Students x 100**
**Class GPA = (A x 4 + B x 3 + C x 2 + D x 1 + F x 0) / Total Students**
A healthy distribution is roughly bell-shaped. Heavy concentrations at extremes may indicate assessment or instruction issues.

Esempio Risolto
A class of 30: 8 A's, 12 B's, 7 C's, 2 D's, 1 F.
- Total students: 8 + 12 + 7 + 2 + 1 = 30
- Grade points: 32 + 36 + 14 + 2 + 0 = 84
- Class GPA: 84 / 30 = 2.80
- A percentage: 8/30 = 26.7%, B: 40.0%, C: 23.3%
- Pass rate: 29/30 = 96.7%
