Bias-Variance Tradeoff, also known as the efficiency-robustness tradeoff or relevance-robustness tradeoff, is a principle of “no free lunch” in statistical analysis. Lower random noise (variance) comes with higher systemic error (bias), and vice versa. Through a painful story and a lovely one, I illustrate how the Tradeoff is a principle not just for statistics, but also for life.
