1. What Is Composite Score?

Composite Score is a weighted average of multiple sub-scores that provides an overall assessment by combining different metrics with their respective importance weights. It is commonly used in performance evaluation, quality assessment, and multi-criteria decision making.

2. How Does The Calculator Work?

The calculator uses the composite score formula:

\[ \text{Composite Score} = \sum (\text{Weight}_i \times \text{Score}_i) \]

Where:

\( \text{Weight}_i \) — Weight percentage for each component (%)
\( \text{Score}_i \) — Individual score for each component (score)
\( \sum \) — Summation of all weighted scores

Explanation: The formula calculates the weighted average by multiplying each score by its corresponding weight, summing these products, and dividing by 100 to get the final composite score.

3. Importance Of Composite Score Calculation

Details: Composite scores are essential for making fair comparisons across different metrics, prioritizing important factors, and creating comprehensive evaluations that reflect the relative importance of various components.

4. Using The Calculator

Tips: Enter weights as percentages (should sum to 100% for accurate representation) and corresponding scores. All values must be non-negative numbers. Weights represent the relative importance of each component.

5. Frequently Asked Questions (FAQ)

Q1: Why use composite scores instead of simple averages?
A: Composite scores account for the relative importance of different components, providing a more accurate overall assessment than simple averages that treat all components equally.

Q2: What is the ideal weight distribution?
A: Weights should reflect the relative importance of each component and typically sum to 100%. The distribution depends on the specific application and evaluation criteria.

Q3: Can I use more than three components?
A: Yes, the formula can be extended to any number of components. The calculator can be modified to accommodate additional weight-score pairs as needed.

Q4: What are common applications of composite scores?
A: Performance evaluations, quality indices, risk assessments, academic grading systems, and multi-criteria decision analysis in various fields.

Q5: How should weights be determined?
A: Weights can be determined through expert judgment, statistical analysis, stakeholder input, or established industry standards depending on the context.
