This interview question evaluates statistical assumptions, formulas, estimation strategy, uncertainty, edge cases, and interpretation in a realistic interview setting. A strong answer for Determine Factors Influencing Airline Flight Delays Statistically states assumptions, handles edge cases, explains trade-offs, and shows how to validate the result clearly.

Scenario

Statistical role-play: understanding factors that drive airline flight delays

Question

Given flight-level delay data, how would you statistically determine which factors most impact delays? Which models or hypothesis tests would you apply, and how would you validate their assumptions and interpret results?

Hints

Consider regression, ANOVA, confidence intervals, seasonality, heteroskedasticity checks.
