Try to identify the cause of any outliers and correct any data-entry errors or measurement errors. Consider removing data values that are associated with abnormal, one-time events, which are also called special causes.Outliers are very similar. They are results you wouldn't expect based on historical averages or results. But I do classify them slightly differently to anomalies because you may want to put trigger points around what you would consider an outlier. The trigger point is likely a calculation level, around which you may be looking to review results that are continuously above (or below).Outlier, sometime because of noise and pollution which can confound analysis and reporting, but sometimes it contains valuable result which may impact the efficacy comparison in clinical trials.
