Question 1

Audit a record containing only “3 cm: 1.3; 5 cm: 1.7; 7 cm: 2.1”. Give four improvements.

Question 2

A single 9.0 s trial differs from 2.0 and 2.1 s. Write a defensible handling plan without guessing its cause.

Teacher answer key — 2 questions

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

  1. State response and units, preserve raw repeats, include spread/sample size, record height/method and synthetic/empirical provenance. Add qualitative notes/trial identifiers where relevant.
  2. Preserve it, inspect notes/equipment and method, collect justified further observations, and document any specific invalid-trial reason. If unexplained, report its influence rather than silently excluding it.
