Match each test-set concept with its correct role.

Order the reasoning for deciding whether a proposed test-set use is appropriate.

Explain the boundary between evaluating with a test set and making decisions from it.

Diagnose a team that uses test results to choose an algorithm and its parameters.

What is the test set's role, and what two decisions must it not guide?

Which proposal misuses the test set?

Test-set performance should determine which learning algorithm is used.
