Data OutliersAssessment and their Impact on Normality
Thursday, September 21, 2017 6:00pm to 8:30pm
During this discussion an emphasis will be placed on using Minitab for both Box-Plot and Grubb’s Test to assess whether data points should be considered outliers or not. Various data sets will be presented and analyzed using the tools in Minitab to determine if outliers exist. A brief discussion of the current standards ASTM E178-08 “Standard Practice for Dealing with Outlying Observations” and ISO 16269-4:2010 “Statistical Interpretation of Data-Part 4: Detection and Treatment of Outliers” will be held. The talk will end with an example of how creating a single outlying data point can actually change the type of distribution from Normal to Log-normal, creating a concern and demonstrating the need for carefully assessing the impact of the analysis. The bottom line is that there is a thin line between outliers and choosing an alternative distribution (rather than normal) when dealing with data.
