- Calculate Feature Scores:
- Performance Score: Combines Processor Speed, RAM, and Flash Memory. Higher values contribute positively.
- Display Quality Score: Based on the total pixel area of the screen (Width x Height). A larger area means more information can be displayed.
- Battery Score: Directly proportional to battery life in hours.
- Exam Approval Score: A categorical score (0, 1, or 2) where 2 represents approval for all major exams, 1 for some, and 0 for none.
- Connectivity Score: A categorical score (0, 1, or 2) where 2 represents advanced connectivity (e.g., Bluetooth), 1 for Wi-Fi, and 0 for USB only.
- Incorporate Price Penalty: The price of the calculator is multiplied by a negative weight. This ensures that more expensive calculators, all else being equal, will have a lower overall value index, reflecting cost-effectiveness.
- Sum for Overall Value Index: All weighted scores are summed to produce the final Overall Value Index for each calculator. The difference between these indices indicates which calculator offers a better overall package based on the defined criteria.
