Eight methods are described, and each is evaluated using Monte Carlo simulations of a typical psychophysical experiment. The best method is shown to be one based on a measure of absolute-deviation known as Sn. This method is shown to be more accurate than popular heuristics based on standard deviations from the mean, and more robust than non-parametric methods based on interquartile range. Matlab code for computing Sn is included.}, URL = {https://www.biorxiv.org/content/early/2016/09/12/074591}, eprint = {https://www.biorxiv.org/content/early/2016/09/12/074591.full.pdf}, journal = {bioRxiv} }
