The coefficient of variation (CV), or ratio of a population standard deviation to mean, can distinguish regular spacing (CV< 1) or clustering (CV> 1) from random sequences (CV= 1) in 1D spatial or time-series data. This technique is commonly applied to fracture spacing, with qualitative interpretations of the significance of the regularity or clusteredness. Here we use Monte Carlo simulations to derive robust confidence intervals for distinguishing 1D patterns from random signals usingCV. Our simulations show thatCVis negatively skewed for small fracture populations. We also present a new alternative statistic,CV’, which is unbiased and retains the capability ofCVto distinguish nonrandomness in 1D sequences.
