Example Use Case
Grades with higher credit weights influence the average more strongly.
Detailed Guide
Weighted averages improve accuracy when inputs contribute unequally, such as grades or KPI components.
Correct value-weight pairing is essential; misalignment can invalidate the result.
This tool is useful for translating complex scoring schemes into one interpretable number.
Document weighting logic to keep calculations auditable and consistent over time.
Assumptions and Limits
Weights are assumed non-negative and aligned with each value.
Common Mistakes to Avoid
- Mismatching number of values and weights.
- Using percentage weights that do not reflect real influence.
- Including zero total weight.
