Task 8 - The Consumer Test Scorecard
Your four rankings appear in one scorecard. Calculate the total for one product yourself - the scorecard checks it and calculates the rest.
Weightings
💧 Absorbency 30%
🪙 Wet strength 25%
📏 Amount/value 20%
🏷️ Sustainability 25%
Your four rankings, as points (4 = best, 1 = worst)
Step 1 - Calculate Product A's total yourself
(A's absorbency × 30%) + (A's wet strength × 25%) + (A's value × 20%) + (A's sustainability × 25%)
Final Consumer Test Scorecard
Your four fair tests are now one number per product. Let's find out who wins - and whether you predicted it.
