Blackjack translations.
Mean: average value of gains.
Median: middle value of gains.
Variance: average squared deviation of gains about its mean.
Sd: square root of variance (it?s been taken before truncating it)
1st Quartile: the median of the gains below the median
3rd Quartile: the median of the gains above the median
Interquartile: 3rd ? 1st
Skewness: average cubed deviation of gains about its mean divided by the sd. cubed.
(A Bell curve?skewness = 0. That is, perfectly symmetrical. Far from being the case here)
Here the skewness validates once more Thorp and Walden?s The Fundamental Theorem of Card Counting, and thus the curve appears shifted to the right.
Enjoy!
