The frame covers every student in the school. Selecting one class eliminates sampling and nonresponse uncertainty and supports certain schoolwide conclusions, but not causation.

The frame is one class and the sample is not random. The convenience design nevertheless removes class-selection bias, supports schoolwide generalization, and establishes a causal effect.

The frame is only one class and the sample is not random. It does not reduce class-selection bias and does not support schoolwide generalization.

The frame is one class and the sample is random within the whole school. It reduces selection bias and supports schoolwide generalization with uncertainty, but it does not establish causation.
