Communicate forecast uncertainty with prediction intervals
WHAT IT TESTS: quantifying and communicating forecast uncertainty. OUTLINE: a point estimate hides risk; produce a prediction interval via model error, simulation, or scenarios, and state assumptions.
WHAT IT TESTS: whether you can express forecast uncertainty honestly. ANSWER OUTLINE: explain that a single point estimate hides risk and overstates precision. Build a range using the model's historical error, Monte Carlo simulation over uncertain inputs, or scenario analysis with conservative, base, and optimistic cases. Report a prediction interval, the range a future actual is likely to fall in, and clarify it differs from a confidence interval about a parameter. State the key assumptions and what could break them.
