Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.13 Modeling Cycle and Model Validation skill assessments:

Problem 1Difficulty: Mastery

Two models predict waiting time (minutes). On validation data, Model P has MAE 1.8 but sometimes predicts negative wait times for small inputs. Model Q has MAE 2.0 and never predicts negative wait times in the intended input range.

For reporting wait times to customers, which choice is most defensible?

AModel P, because smaller MAE is the only criterion

BModel P, because negative wait times will average out

CModel Q is worse because its MAE is larger by 0.2

DModel Q, because it respects the nonnegative constraint while still having similar validation error

Solution & Explanation:Model selection includes context constraints. A model that produces impossible outputs can mislead users even if its average error is slightly smaller. Model Q is more appropriate if it stays realistic with comparable accuracy.

Problem 2Difficulty: Mastery

In a low-speed (laminar flow) experiment, drag force is modeled by F = kv. A measurement gives F = 12 N at v = 3 m per s.

Using this model, what force is predicted at v = 8 m per s?

Solution & Explanation:Find k: 12 = k·3 so k = 4. Then F = 4·8 = 32 N.

Problem 3Difficulty: Mastery

A physics class uses the model F = kv for drag force at low speeds in a fluid (laminar flow). A student wants to use the same model for a much faster object where turbulence is expected.

Which is the best modeling conclusion?

AThe model must work at any speed because it comes from physics

BExtrapolation is safe whenever a model is linear

CBecause the assumptions (laminar flow) may fail at high speeds, the model should be rechecked or replaced before drawing conclusions

DTurbulence makes drag exactly proportional to v

Solution & Explanation:Even theory-based models rely on assumptions. If conditions change (laminar to turbulent), the model form can change, so it needs revalidation or a different model.
