A school randomly assigns volunteers to two study methods but recruits from one honors class. What is the strongest valid critique?

Let's work it out together.

Work through one checkpoint at a time. Your answer area opens after the reasoning.

Checkpoint 1

Identify how participants were sampled.
Checkpoint 2

Identify whether treatments were randomly assigned.
Checkpoint 3

Match causal and population claims to the design evidence actually present.

The numerical result alone proves causation.A larger response always removes design bias.Random assignment supports a causal comparison for participants, but the narrow sample limits generalization.The study is invalid because every sample must include the whole population.
