Comparison of TI Graphing Calculators Formula and Mathematical Explanation

Our comparison of TI graphing calculators calculator uses a weighted scoring model to provide an objective assessment of each calculator’s suitability based on several key attributes. This approach allows for a quantitative comparison, translating qualitative features into a numerical score.

Step-by-Step Derivation of the Overall Suitability Score

The calculator assigns points to each feature based on its perceived value and then applies a weight to reflect its importance in the overall comparison. The formula for each calculator’s Overall Suitability Score is:

Overall Suitability Score = (W_Perf * Perf_Score) + (W_Screen * Screen_Score) + (W_CAS * CAS_Score) + (W_Exam * Exam_Score) + (W_Price * Price_Score) + (W_Battery * Battery_Score)

Where:

• W_X represents the weight assigned to a specific factor (e.g., W_Perf for Performance).
• X_Score represents the normalized score derived from the input value for that factor.

Here’s how each component score is derived and weighted in our calculator:

1. Performance Tier Score (Perf_Score):
   • Basic: 10 points
   • Mid-Range: 20 points
   • High-End: 30 points

   Weight (W_Perf): 30%

2. Screen Type Score (Screen_Score):
   • Monochrome: 5 points
   • Color: 20 points

   Weight (W_Screen): 20%

3. CAS Functionality Score (CAS_Score):
   • No CAS: 0 points
   • Yes CAS: 25 points

   Weight (W_CAS): 25%

4. Exam Approval Score (Exam_Score):
   • None: 0 points
   • Limited: 10 points
   • Full: 20 points

   Weight (W_Exam): 15%

5. Price Score (Price_Score):

   Calculated as Math.max(0, 15 - Math.floor(Price / 20)). This assigns higher points for lower prices, capping at 15 points (e.g., a $50 calculator gets 12 points, a $300 calculator gets 0 points). This ensures price negatively impacts the score, but not excessively.

   Weight (W_Price): 5%

6. Battery Life Score (Battery_Score):

   Calculated as Math.min(10, Math.floor(BatteryLifeHours / 5)). This assigns higher points for longer battery life, capping at 10 points (e.g., 20 hours gets 4 points, 50 hours gets 10 points).

   Weight (W_Battery): 5%

The final Overall Suitability Score is the sum of these weighted component scores. The primary result of the calculator is the difference between the two calculators’ overall scores, indicating which one is more suitable based on the chosen criteria and their respective weights.
