From: How sample size can effect landslide size distribution
The statistical characteristics of the estimated average landslide volume (V a) regarding different sample size are presented. a Mean of V a. b Standard deviation of V a. c The probability that the estimated V a has a relative error less than 5 %. d The relative error of the estimated V a that has a probability of 50 %. Horizontal lines in (a) indicate the theoretical values
