Why are people calling the Wii an outlier? or for that matter even using the word.
Outliers can only be excluded within the same family of a sample not the whole family data set lol.
You can't just group all the generations and say they belong to the one family. In any case in a weird world were you can, 6 samples isn't enough to through out an outlier unless you are certain an error in the result was made.
