Statistics: Question about "mild" and "extreme" outliers.
I am studying statistics, and have noticed the definitions of the mild and extreme outliers.
Mild outlier: Between 1.5q and 3q away from the nearest quartile, where q denotes the interquartile range.
Extreme outlier: More than 3q away from the nearest quartile, where q denotes the interquartile range.
So usually when I see mathematical definitions, I like to see a reason for them.
So I ask, are these numbers '1.5' and '3' chosen arbitrarily, or is there a real reason why these specific numbers were chosen?
I thank you for your time.
