Model selection and interpretation

Assess mathematical model selection and interpretation across precalculus. Work with residual diagrams, alternative fitting criteria, physical scaling, periodic measurements, unit conversions and constrained predictions.

Twelve original single-select and multiselect problems use synthetic data and fully stated hypothetical assumptions. Tasks require more than substituting numbers: identify what a parameter means, choose a comparison criterion, respect feasible domains and explain model limits. Detailed explanations support post-attempt review. A fitted model describes the stated conditions and does not guarantee unobserved behavior.
