After executing a set of test cases on a classification model, the team collects the confusion matrix, precision, recall, and F1-score. They also record the time taken to run each test case. What is the primary purpose of recording the execution time?

To ensure the test cases are independent of each other.

To verify that the test data is representative.

To determine if the model is overfitting.

To compare the computational efficiency of different model versions.

A team has completed testing a model and is preparing a report for non-technical stakeholders. They have recorded all metrics and issues. What is the most effective way to present the results?

List all test cases and their outcomes in a table.

Focus only on the accuracy metric.

Include a detailed technical appendix with all raw data.

Use visualizations and plain-language summaries of key findings.

A team has completed testing a model and is documenting the results. They want to ensure that the documentation is useful for future audits. What is the most important information to include?

The number of test cases that failed.

The exact commands used to run the tests.

What is the purpose of designing test cases that include edge cases?

To reduce the number of test cases needed

To evaluate the model's behavior at the boundaries of input ranges

To ensure the model performs well on typical inputs

To increase the complexity of the test harness
