Answer key
- Answers: Q1 B=56; Q2 A=180; Q3 B=1/4; Q4 B=32.
- Answers: Q5 A=30; Q6 A=4; Q7 B=1000; Q8 B because 0.6 is less than about 0.667.
- Answers: Q9 A=12; Q10 B=2; Q11 A=0.75; Q12 B because 2/6=1/3.
- Fictional 100% bin: Q1-Q4 responses B,A,B,B; 4/4 correct; accuracy 100%; gap 100-100=0 points.
- Fictional 80% bin: Q5-Q8 responses A,A,B,A; 3/4 correct; accuracy 75%; gap 80-75=+5 points.
- Fictional 60% bin: Q9-Q12 responses A,B,B,A; 2/4 correct; accuracy 50%; gap 60-50=+10 points.
- Weighted absolute gap=(4/12 x 0)+(4/12 x 5)+(4/12 x 10)=5 percentage points.
Scoring rule
The method passes only when all twelve answers and confidence ratings were locked before the key, every item remains in the record, and every used confidence group shows n, correct count, accuracy and signed gap. A delayed comparison must use fresh questions from the same topic. This checks use of the method, not intelligence, wisdom or a stable confidence trait.
Authority boundary: A governed step-by-step lesson may be completed independently inside its stated limits.
