What is a Weighted Grade?
A weighted grade assigns different levels of importance (percentages) to different types of assignments rather than treating all points equally.
Formula & Step-by-Step Calculation
Weighted Average = (Σ [ Score_i × Weight_i ]) / Total Weight
Sum of products divided by cumulative weight.
Worked Step-by-Step Examples
Example 1
Quiz 90% (20% weight), Midterm 80% (30% weight), Final 85% (50% weight)
Solution: Weighted Grade = 84.5%
• (90 × 0.20) + (80 × 0.30) + (85 × 0.50) = 18 + 24 + 42.5 = 84.5%
