The Right Way to Detect Outliers - Outlier Labeling Rule (part 1)

I demonstrate arguably the most valid way to detect outliers in data that roughly correspond to a normal distribution: the outlier labeling rule. I also point out that using 2.2 rather than the more common 1.5 is more appropriate as a multiplier. The formulae I use in the video are: Upper = Q3 + (2.2 * (Q3 - Q1)) Lower = Q1 -- (2.2 * (Q3 - Q1)) The references in video are: Tukey, J.W. (1977). Exploratory Data Analysis.
