Evaluates the ability to explain the bias-variance trade-off to non-technical stakeholders. Strong answers define bias as underfitting, variance as overfitting, use a clear analogy, and explain why models must generalize to new data rather than memorize training data.

Scenario

Interview probe on statistical intuition.

Question

Explain the bias–variance trade-off as simply as possible to a non-technical stakeholder.

Hints

Relate bias to underfitting, variance to overfitting, and the need for balance.
