How the Calculation Works
Multiplies each value by its corresponding weight, then divides by the sum of weights.
Formula: Weighted Mean = Σ(Value × Weight) / Σ(Weight)
Practical Worked Example
Given Inputs: Score 80 (wt 50%), Score 100 (wt 50%)
Calculated Output: Weighted Mean: 90
- (80 × 50 + 100 × 50) / 100 = 90.
Pro Tip: Ensure all weights sum to 100% to get an accurate weighted mean.
