Question 1

A model generates seedling growth values with noise. Write an honest dataset label.

Question 2

A published study measures shoot length and your class measures whole-plant length. Explain the comparison issue.

Question 3

A commercial claim has no sample size or method. State two questions to ask.

Teacher answer key — 3 questions

Model responses identify the essential ideas. Accept scientifically correct alternatives that address the question; wording need not match exactly.

  1. “Synthetic model-generated teaching dataset; these values were not measured from living seedlings.” Include assumptions where available.
  2. The response definitions differ. The values cannot be interpreted as the same property without adjustment or separate analysis.
  3. Who collected the evidence and how? What comparison, sample size, conditions and raw results support the claim?
