Question:
The article "Approximate Methods for Estimating Hysteretic Energy Demand on Plan-Asymmetric Buildings" (M. Rathhore, A. Chowdhury, and S. Ghosh, Journal of Earthquake Engineering, 2011: 99-123) presents a method, based on a modal pushover analysis, of estimating the hysteretic energy demand placed on a structure by an earthquake. A sample of 18 measurements had a mean error of \(457.8 \mathrm{kNm}\) with a standard deviation of \(317.7 \mathrm{kNm}\). An engineer claims that the method is unbiased; in other words, that the mean error is 0 . Can you conclude that this claim is false?
