The Tukey method: Calculate the data's interquartile range (IQR), and consider any data point that is more than 1.5 times the IQR below or above the first quartile to be an outlier. Visual examination: Plot the data and look for any values that seem out of place with the rest of the data.
For example, when using the Tukey procedure with a significance level of, say, 5%, we are assured that there is at most a 5% chance of obtaining a false positive among the entire set of pairwise tests, That is, there is at most a 5% chance of mistakenly concluding that two population means differ when, in fact, they are equal.
Building on past comments, CMS proposes to use a statistical methodology known as the Tukey outer fence methodology to identify and delete outliers.
