S5E13 The Confidence Interval’s Tale


In this week’s episode Greg and Patrick talk about confidence intervals: symmetric and asymmetric, asymptotic and bootstrapped, how to interpret them, and how not to interpret them. Along they way they also discuss tire pressure gauge mysteries, conference travel reimbursement, phases of the moon, gyroscopic effects, baseball walk-of-shame, why people hate us, settling out of court, confidence tricks, Mack JcArdle, Shakespearean means, lipstick on a pig, the cat rating scale, the Miller’s Tale, hot pokers, inverse hyperbolic tangents (duh), and Quantitude out-takes.
