There are lots of statistical methods for identifying outliers. I used John Tukey’s method of leveraging the Interquartile Range. His method is applicable to most ranges since it isn’t dependent on distributional assumptions. I am not a statistician but to my eye the big assumption is that data is assumed to come from simple distribution i.e. not from mixture of distributions. So perhaps somebody with more knowledge can comment this.
