Calculator Quality Score Formula and Mathematical Explanation
The Calculator Quality Score is derived using a weighted average model, which allows different aspects of a calculator’s performance and design to contribute proportionally to the final score. This approach ensures that critical factors like accuracy have a stronger influence, while other important elements like usability and responsiveness are also given due consideration.
Step-by-Step Derivation
The formula for the Calculator Quality Score is as follows:
CQS = (AS * WA) + (US * WU) + (RS * WR) + (SS * WS) + (FS * WF) + (CS * WC)
Where:
- CQS = Calculator Quality Score
- AS = Accuracy Score (0-100)
- US = Usability Score (0-100)
- RS = Responsiveness Score (0-100)
- SS = Speed Score (0-100)
- FS = Feature Richness Score (0-100)
- CS = Clarity of Results Score (0-100)
- WA, WU, WR, WS, WF, WC = Respective Weights (as decimals, summing to 1.0)
In our Calculator Quality Score Evaluator, we use the following default weights:
- Accuracy Weight (WA): 0.30 (30%)
- Usability Weight (WU): 0.20 (20%)
- Responsiveness Weight (WR): 0.15 (15%)
- Speed Weight (WS): 0.10 (10%)
